We have fabricated III–V gain region/Si waveguide hybrid lasers with an InP-based two-storied ridge structure using direct bonding technology. Continuous-wave operation at a temperature of 20 °C with a threshold current as low as 30 mA was obtaine

The influence of CO, CO2 and H2O gases on the stability of negative-electron-affinity (NEA) GaAs photocathodes during operation is investigated in the present work. We have found that exposure both to H2O and CO2 decreases the photocurrent of the pho

We examine the flash desorption of Cs from NEA surfaces, and measure the workfunction change during NEA activation. The lifetime changes on NEA photocathodes under the operation of decay and reactivation cycles are also measured. The thickness and st
