We present amorphous silicon solar cells on random and periodic back reflector geometries. 1D gratings offer an intuitive understanding of the light trapping process by excitation of guided modes. Using the same period and similar shape, better performance is observed on 2D gratings due to a higher number of resonances.

We demonstrate a cascaded re-modulation scheme in WDM-PON based on FP-LD and RSOA. Experimental results show that this scheme can successfully demodulate 10Gbit/s downstream DPSK signal and improve upstream transmission performance simultaneously.

We propose channel drop filters based on waveguide cavities. The proposed filters operate in Gires-Tournois-like resonator regime that includes a 100% reflecting rear mirror. Typical lengthes of the proposed filters are less than 15 μm.

All optically driven micromachines can use angular momentum of light to achieve their functions. These micromachines are produced by two photon photopolimerisation process or by producing new materials with a significant birefringence. Applications of these machines will be discussed.

A near-infrared wide-band polarization-insensitive absorber is demonstrated. It is composed of two-dimensional titanium disk arrays and a gold plate. The absorption at normal incidence is above 90% in the range of 164.2THz to 345.2 THz.
