We demonstrate a 1}16 optical packet switch sub-system for 160 Gbps RZ-OOK and 12}10 Gbps multi-wavelength DPSK packets. We show error-free operation with maximum penalties of 0.7 dB for 160 Gbps RZ-OOK and 0.6 dB for multi-wavelength DPSK packets.

There has been a lot of interest in developing high-performance terahertz imaging systems which have valuable applications in surveillance, security screening, medical tomography and nondestructive inspection of various pharmaceutical, agricultural, and industrial products [1, 2]. Conventional terahertz imaging systems based on mechanical scanning of the imaging beam, object or the detector suffer from significantly low acquisition speeds [3–5]. Additionally, realtime terahertz imaging systems based on two dimensional arrays of THz sources and detectors tend to have lower sensitivity, higher complexity and higher operational cost [6–8].

We present technological bricks and concepts under study which could permit build up of future THz remote sensing systems. Critical issues regarding such systems mainly rely on the availability of sensitive and compact detectors together with powerful and versatile sources. Potential use of plasma waves in nano-transistor is presented which can be exploited for the realization of an efficient mixer operating at THz frequencies to be implemented in a coherent detection scheme. In such a scheme the necessary local oscillator is obtained from a solid state dual frequency laser whose architecture is also detailed. On the emitter side, the preliminary realization of sub-millimeter wave to THz amplifier based an vacuum tube technology, including carbon nano-tubes is also presented.

We systematically characterized semiconductor-metal core-shell plasmonic nanolasers of various sizes and shapes under electrical injection. New experimental results will be presented including detailed temperature-dependent and duty cycle dependent performance measurements, as well as polarization measurements.

We report a new family of ultra-fast all-optical wavelength converters. The device architecture employs a single SOA and filtering elements integrated in silicon-on-insulator substrates. These schemes enable high-integration density and low power consumption.

Optical imaging is unequivocally the most versatile and widely used visualization modality in clinical practice and life sciences research. In recent years, advances in photonic technologies and image formation methods have received particular attention in biological research and the drug discovery process for non-invasively revealing information on the molecular basis of disease and treatment. An increasing availability of endogenous reporters such as fluorescent proteins and probes with physiological and molecular specificity enable insights to cellular and sub-cellular processes through entire small animals, embryos, fish and insects and have revolutionized the role of imaging on the laboratory bench, well beyond the capability of conventional microscopy. This talk describes current progress with instruments and methods for in-vivo photonic tomography of whole intact animals and model biological organisms. We show how new tomographic concepts are necessary for accurate and quantitative molecular investigations in tissues and why it could be potentially a valuable tool for accelerated investigations of therapeutic efficacy and outcome. We further demonstrate that cellular function and bio-chemical changes can be detected in-vivo, through intact tissues at high sensitivity and molecular specificity. Examples of imaging enzyme up-regulation, carcinogenesis and gene-expression are given. The potential for clinical translation is further outlined. Limitations of the method and future directions are also discussed.

We present a scheme for dual-wavelength operation of a diode-pumped Cr3+:LiCaAlF6 (Cr3+:LiCAF) laser with tunable frequency difference based on external optical feedback from a Littman-mounted diffraction grating. The maximum spectral separation achieved allows a frequency separation from 0 to 9 THz in the 785 nm region.
