Recently, more and more applications require amplifier systems delivering high power, short-pulsed radiation with the full repetition rate of the mode-locked oscillator. In the frequency domain, the output spectrum of the stabilized mode-locked laser consists of equidistant narrow lines separated by the laser repetition rate, often called “frequency comb”. So far, to drive highly non-linear processes directly by frequency combs requires special efforts because of the limited average output power from the mode-locked oscillator. Passive cavity amplifiers have been built to generate frequency combs in the ultra-violet region by high-order harmonics generation. For these applications, power amplifiers that can amplify short pulses from the oscillator will be an ideal tool to further improve available pulse energy at high repetition rates. In frequency comb applications, extra phase noise that is added from the amplifier has to be minimised to preserve pulse-to-pulse phase coherence. In the time domain, phase-locked amplifier system may deliver pulse trains with identical intra-pulse electric field shape. With sufficiently high pulse energy and short pulse width, it is possible to investigate carrier envelope phase dependent phenomena, such as electron emission by field ionisation and high harmonics generation. In these experiments, it is sometimes advantageous to have a high repetition rate system to obtain enough statistics for rare events in short measurement times.

Photonic crystal fiber (PCF) has proven very useful for enhancing light-matter interactions, offering interaction lengths much longer than those available using conventional techniques. A well-defined optical mode propagating through a microfluidic channel or gas cell offers a unique way of carrying out absorption spectroscopy in very small sample volumes (∼1 µL) [1–3]. Additional advantages of PCF include its flexibility and the opportunity for system miniaturization. In this paper, we demonstrate the use of hollow-core photonic crystal fiber (HC-PCF) as a highly-controlled (photo)chemical microreactor in which reaction dynamics can be monitored in real-time via broadband spectroscopy. Strong confinement of both sample and light in the core region results in enhanced reaction dynamics and strongly reduced laser power requirements.

Quantum control of photochemical processes such as photodissociation or photoisomerization can be realized by controlling wave-packet dynamics towards the reaction coordinate on the excited-state potential surface. We already demonstrated “real-time wave-packet engineering” by combining a highly sensitive wave-packet spectrometer, which enabled us to measure the time-resolved difference transmission spectra at 20 frame-persecond, with a computer-controlled pulse shaper [1]. We were successful in selectively exciting mode-specific motion of a wave-packet related to either the twisting or bending mode individually [2].

It has been predicted theoretically [1] that counter-propagating parametric interactions, where the signal and idler waves are propagating in opposite directions, will establish a distributed feedback mechanism and thus optical parametric oscillation without the need to apply mirrors or external feedback cavity. Such a device, the mirrorless optical parametric oscillator (MOPO), has been recently realized by employing engineered nonlinear crystals, namely, periodically poled KTiOPO4 (PPKTP) with the periodicity of the structure of 800 nm [2]. One of the remarkable properties of the MOPO was a strong asymmetry in spectral content of the signal and idler pulses, where signal pulse bandwidth was of the same order as that of the pump while the counter-propagating idler was about two orders of magnitude narrower than the signal. In this work we provide experimental and theoretical investigation on the temporal phase transfer characteristics in MOPO. In particular we show that the phase modulation is transferred primarily to the signal wave while the idler wave remains almost phase-modulation-free. This property allows a simple means for generating transform-limited pulses in mid-infrared spectral region regardless of phase modulation of the pump. Theoretical simulation reveals that the amount of remaining phase modulation in the idler wave depends on the group-velocity mismatch between the co-propagating pump and signal waves.

Optical solitons are nondispersive nonlinear waves that are supported through a balance between group-velocity dispersion (GVD) and nonlinearity. The so-called dispersive waves are linear waves phase-matched to these solitons, and are often found in supercontimuum generation [1, 2]. The dispersive wave wavelength can be predicted from a phase-matching condition to the solitonic wave [3]. This phase-matching point is often interpreted as being located where solitons are no longer supported, i.e. where the GVD changes sign. However, in reality the dispersive wave is found at the wavelength where the total dispersion of the generated soliton is changing sign.

In present work we focus on synthesis and properties of Au-ZnO nanocomposite and demonstrate its applications. Au-ZnO nanocomposites were synthesized by atom beam co-sputtering and sequential annealing. Optical absorption studies revealed the tunable surface plasmon resonance of gold nanoparticles. Annealing beyond eutectic temperature resulted in formation of Au-nanoparticles supported by ZnO nanorods as confirmed by high resolution transmission electron microscopy. Au-ZnO nanocomposite was used to study the surface enhanced Raman spectroscopy in fullerene molecule (C70). The Au-ZnO exhibits excellent switching behaviour enabling its potential use in day-today life.

A new concept for the generation of terahertz (THz) radiation is presented. Instead of accelerating carriers in an external bias field as state-of-the-art THz emitters generate THz radiation [1], the THz radiation is generated by lateral Photo-Dember currents induced by inhomogeneous optical excitation [2]. We prove the principle in the simplest geometry on GaAs.

We report on thermal bleaching measurements of photodarkening-induced color centers in ytterbium-doped silica fibers. We make use of the similarity between UV and photodarkening-induced defects and apply a model, developed to describe and predict the performance of thermal decay of UV-induced fiber Bragg gratings [1], to study the thermal binding energy associated with photodarkening-induced color centers. This model assumes a broad distribution of trap sites, with the rate of thermal depopulation being an activated function of the trap depth [1]. Fraction of depopulated traps is uniquely defined by the demarcation energy Ed, with traps having energy greater than Ed remaining unchanged. Time t and temperature T are related through Ed = kBT·ln(v0t), where kB=8.62·10−5 eV/K is Boltzmann's constant and v0 is a frequency term (attempt frequency), obtained by acquiring datasets at different temperatures and fitting them together.

We present a versatile approach that allows for both precise and broadband measurements of transmission spectra by transferring the precision of an optical frequency comb to a mode-hop free tunable external cavity diode laser. The advantage of using a tunable diode laser compared to other methods such as direct frequency comb spectroscopy [1] or multi-heterodyne spectroscopy [2] is the ability to resolve spectral features that are much smaller than the repetition rate of the employed frequency combs (for instance the MHz-linewidth modes of an ultra high-Q microcavity). The potential of the technique is demonstrated by measuring for the first time the small residual dispersion of optical microcavities [3,4]. Figure 1 depicts the measurement setup that has been used for broadband spectroscopy of the mode structure of a microresonator.

Silicon photonics is a rapidly developing platform for integrated optics. Combining the low-loss passive silicon photonic circuitry with III–V based active optical functionality, we can combine the best of both worlds. We investigate a new optical platform based on the heterogeneous integration of InP-based active 2D Photonic Crystals (PCs) on SOI waveguides.
