Silicon photonic crystal filter with ultrawide passband characteristics.

We report on what is believed to be the first example of an ultrawide, bandpass filter, based on a high-contrast multicomponent one-dimensional Si photonic crystal (PC). The effect of the disappearance of a limited number of flat stopbands and their replacement with extended passbands is demonstrated over a wide IR range. The passbands obtained exhibit a high transmission of 92% to 96% and a su...

Passband switchable microwave photonic multiband filter

A reconfigurable microwave photonic (MWP) multiband filter with selectable and switchable passbands is proposed and experimentally demonstrated, with a maximum of 12 simultaneous passbands evenly distributed from 0 to 10 GHz. The scheme is based on the generation of tunable optical comb lines using a two-stage Lyot loop filter, such that various filter tap spacings and spectral combinations are...

Photonic crystal filter integrated with photodiodes

We demonstrate the monolithic integration of photonic crystal waveguides, a photonic crystal demultiplexer, a conventional waveguide and photodiodes in InGaAsP-based material. The photonic crystal demultiplexer consists of hexagonally arranged air holes. The inputted light at the wavelengths of 1530nm and 1550nm can be separated by the demultiplexing system.

Investigation of thermal tunable nano metallic photonic crystal filter with mirror symmetry

Using the transfer matrix method, the effect of temperature on thetransmission spectra of thermal tunable nano metallic photonic crystal filter has beeninvestigated. Three different materials H (high refractive index material), L (lowrefractive index material) and M as a metallic layer, have been used to make thisstructure. M layer is considered to be Silver. The complex refractive index of Sil...

Mechanically switchable photonic crystal filter with either all-pass transmission or flat-top reflection characteristics.

We theoretically introduce a new type of optical all-pass filter based on guided resonance in coupled photonic crystal slabs. The filter exhibits near-complete transmission for both on- and off-resonant frequencies and yet generates large resonant group delay. We further show that such a filter can be mechanically switched into a flat-top band rejection filter.
