The quantum yield formula for uniform-doping GaAIAs/GaAs transmission-mode photocathodes is revised by taking into account the light absorption in the window layer.By using the revised quantum yield formula,the domest...
Based on the theory of four-port resonator filters, the characteristics of four kinds of filters with single race-track, dual race-track, rectangular and MMI resonators respectively were numerically simulated by utili...
