spatial demultiplexer

A new design method for multilayer thin film spatial demultiplexer based on Superprism phenomenon of periodic photonic crystal is presented.Without ralph lauren polo shirts complex techniques, the multilayer thin film structure is deposited easily with Lacoste Polo Shirts increasing the thickness of the single layer and decreasing the periodicity. Multiplayer structure is more feasible in practice for fabrication. Finally, we study the integration of the structure and Cheap Lacoste Polo Shirts detector , and calculate the quantum efficiency of the device . 3、A wavelength selective monolithically integrated photodetector array has been fabricated and characterized, which can be used for chi straightener reconfigurable optical add-drop multiplexers. The device operates at a wavelength around 1500nm for four polo shirts channels with 10nm interval. A spectral linewidth as narrow as 0.8nm, an external quantum efficiency of about 12 %, and a 3dB bandwidth of 8.2GHz were obtained in the device.
