We optimized a compact photolithographically fabricated photonic crystal DeMUX and obtained flat and high transmittance between channels. A thermal analysis showed that a footprint of 110 um2/ch is possible with PhC technology.

We describe the fabrication and a demonstration of passive and active photonic crystal nanocavity devices, namely an electro-optic modulator, an all-silicon photodetector and a DeMUX filter. This is the first demonstration of active and passive photo

We demonstrate ultrasmall demultiplexers based on photolithographic photonic crystals. The footprint of the demultiplexers is 110 μmsup2/supper channel. Our in-plane demultiplexers are clad with silica, which makes them stable and easy to integrate

We photolithographically fabricate a high-Q photonic-crystal nanocavity with a silicon dioxide clad structure and demonstrate an electro-optic modulator, a photoreceiver, and a DEMUX, all of which are easy to integrate with other silicon photonic dev

Silicon photonic crystal (PhC) nanocavity fabricated on a two-dimensional slab is attractive due to their small size and high-Q, which allow us to study optical nonlinearity at an extremely low input power. However, it has been fabricated by using el

We fabricate and demonstrate an electro-optic modulator that utilizes the randomness in a photonic crystal waveguide. We exploit a way of using random photonic crystals for device application that involves restricting the area influenced by the rando

High Q optical cavities are employed to realize a coupled cavity system with which to achieve optical signal processing. Photonic crystal (PhC) nanocavities are particularly attractive because they are suitable for integration. However, they usually

A hollow bottle-like microresonator (BLMR) with ultra-high quality factor is fabricated from a microcapillary with nearly parabolic profile. At 1.55 $\mu m$ pumping, degenerate four-wave mixing can be observed for a BLMR of diameter 102 $\mu$m. The p

We demonstrate a demultiplexer with a small footprint, dense spacing and tunability obtained using a photolithographic photonic crystal. Eight-port demultiplexing with a 267 GHz spacing is demonstrated with high wavelength tunability.
