A detailed structural and optical characterization of single GeSn nanowire, Si/GeSn and Ge/GeSn core/shell nanowire is presented. Polarization-dependant reflectance as well respon-sivity measurement were used to investigate the optoelectronic response of these nanostructures. Theoretical investigations will complement the experimental work.

We review recent advances of InGaAs-channel grating-gate high-electron-mobility transistors as fast, highly sensitive, room-temperature-operating THz detectors for THz wireless communication systems and THz imaging/sensing systems. We experimentally demonstrated that the gate-readout of the photovoltage from a detector, instead of the conventional drain-readout, simultaneously enables the scaling of the photovoltage with the active area size, the impedance matching with 50-Ω interconnection systems, and enhancement of the responsivity owning to the “3D rectification effect”.

We review our recent progress on the all-optical signal processing technologies using the nonlinear bidirectional semiconductor optical amplifier (NB-SOA) unit, enabling the functions of the optical phase conjugation (OPC) conversion and the phase-preserving amplitude regeneration for QPSK signals at the same time.

We have developed an algorithm for (re)configuration of Coupled Resonator Optical Waveguides filters. We analyze in detail the effect of the phase shift introduced by tunable Mach-Zehnder interferometers. An alternating pattern is proposed to drive every other tunable coupler. We verified this algorithm to realize a user-defined all-pole filter function in circuit simulation.

In this paper, we present the use of a microdisk to provide scalable and reconfigurable optical logic functions, by introducing an overlay of an optical phase change material. The microdisk switches can be serially-coupled to realize non-volatile switching for wavelength-selective spatial routing.
