We demonstrated the direct modulation of photonic-crystal nanocavity lasers to realize on-chip optical interconnects. A maximum 3-dB bandwidth of 16.2 GHz was obtained. We achieved a 17-Gb/s eye opening with a 35.3-fJ/bit energy cost.

We studied the effect of HCl, H3PO4, HBr etchants, temperature, illumination on the display of dislocation pits on <;100> InP single crystal wafers, and analyzed the effect of illumination, using the wet chemical etching method. The experimental results show that the etching rate is strongly dependent on the proportion of HBr in the mixed etchant and HBr alone can reveal dislocation pits on <;100> InP wafers. Both illumination and higher temperature can increase the etching rate. We also discuss the mechanism of different sizes of dislocation pits.

We introduce a new class of quantum dot-based devices, in which the semiconductor structures are integrated on top of piezoelectric actuators. This combination allows us on one hand to study in detail the effects produced by variable strains (up to about 0.2%) on the excitonic emission of single quantum dots and on the other to manipulate their electronic- and optical properties to achieve specific requirements for their use in quantum optics experiments and possibly future devices for quantum communication.

The material quality at high-k interfaces are a major concern for FET devices. We study the effect on two types of InAs nanowire (NW) transistors and compare their characteristics. It is found that by introducing an inner layer of Al2O3 at the high-κ interface, the low frequency noise (LFN) performance regarding gate voltage noise spectral density, SVg, is improved by one order of magnitude per unit gate area.

InP/Si substrate has been fabricated by employing wet-etching and wafer direct bonding technique. The surface of the InP/Si substrate was very smooth and no strain was observed. On top of the substrate, InAs/InP quantum dots (QDs) have been monolithically grown using metal organic vapor phase epitaxy (MOVPE). According to photo-luminescence (PL) measurement, almost the same intensity, peak wavelength and full width half of maximum (FWHM) have been observed compared to QDs on InP substrate.

Ruthenium (Ru) as the semi-insulated doping material for InP has good characteristics in terms of the capacitance and heat dissipation of the current blocking layer for Laser Diodes. However unintentional Zn diffusion from adjacent p-InP into Ru-InP causes the degradation of Laser characteristics such as the output power. In this paper, we fabricated p-InP/Ru-InP/pInP (p/Ru/p-InP) structure by Metalorganic Vapor Phase Epitaxy (MOVPE) and analyzed the behavior of Zn diffusion from Zn-InP into Ru-InP after annealing by SIMS measurement.

We report for the first time the passive mode-locking of single section Fabry-Perot (FP) lasers based on InAs quantum dots grown on (113)B InP substrate. Devices under study are a 1 and 2 mm long laser diodes emitting around 1.58 μm. Self-starting pulses with repetition rates around 39 and 23 GHz and pulse widths down to 1.5 ps are observed after propagation through a suitable length of single-mode fiber for intracavity dispersion compensation.

We demonstrate a monolithically integrated quadrature coherent receiver photonic integrated circuit (PIC) on an InP substrate with a 90° optical hybrid, a variable optical attenuator (VOA) and four pin-photodetectors. With an attenuation of more than 20dB the VOA enables the usage of the receiver PIC for colourless WDM detection.

We report on an extremely-high sensitive terahertz (THz) detector based on our original asymmetric dual-grating gate high electron mobility transistors (A-DGG HEMTs) designed and fabricated using InAlAs/InGaAs/InP material systems. The obtained responsivity is 22.7 kV/W at 200 GHz. To the best of our knowledge, this value is the record responsivity ever reported for this frequency range at room temperature.

Mode-locking of single-section Fabry-Pérot lasers based on InAs/InP quantum dashes is studied by second-harmonic generation frequency-resolved optical gating (SHG-FROG). The devices take advantage of an optimized epitaxial structure with modal gain of 50 cm-1 showing a broad and flat emission spectrum of width in excess of 14 nm. Self-starting pulses of a width down to 430 fs are observed after intracavity dispersion compensation using single-mode fiber (SMF).
