We developed an InP-based photodetector which was bonded on a CMOS wafer containing a Si3N4-wiring photonic circuit. The detector fabrication is compatible with wafer scale processing steps, guaranteeing compatibility towards future generation electronic IC processing. Integration technology and experimental results are presented in this paper.

Characteristics of a semiconductor laser subject to DC-offset optical pulse injection are investigated numerically. By injecting pulses with a repetition rate of 1 GHz, frequency multiplication up to 10 GHz and division at 500 MHz are demonstrated.

Photon manipulation at the `surface' of three-dimensional photonic crystals has been demonstrated. It is shown that photons can be confined and propagate through surface states, and strong 3D localization of photons (Q ges 9000) has been achieved.

To enable high-speed communication over atmospheric turbulence channels, we propose to transmit LDPC-coded sequence over FSO and wireless channels, feedback channel state information of both channels by RF-feedback, and adapt powers and rates so that total channel capacity is maximized.
