摘要
A diffraction grating LAYER REFLECTOR SUPERIOR (103 or 203) of an optical waveguide REFLECTING nonresonant, is used to extract energy of a selected wavelength from layer guide WAVES (102 or 202) the layer REFLECTING. In one embodiment, the layer REFLECTING (103) is designed as a gain medium WHICH PUMPS IN THE AREA OF A GRILLE (120), AND FINISHING OPTICALLY AT EACH END OF THE DEVICE AS THE EXECUTION SERVES AS A LASER WITH A GREAT Cavity SUPPLIED BY LAYER GUIDED WAVES (102) WILLING TO GAIN IN THE AREA OF SHORT GRILLE. IN A SECOND EXECUTION reflective layer (203) IN THE AREA OF A GRILLE (211) has an opposite conductivity dopant from that LAYER GUIDED WAVES (202) such that the device in this area can be reverse biased FOR SERVE AS A photodetector WAVELENGTH SELECTIVE. Placing two photodetectors Wavelengths in TANDEM WITH GRIDS (211 and 212) of different STEPS TO OBTAIN A photodetector demultiplexer wavelengths.
