Lasing characteristics of In Ga As ∕ In Ga As P multiple-quantum-well waveguide-type depleted optical thyristor with vertical window

This study demonstrates the lasing characteristics of In Ga As ∕ In Ga As P multiple-quantum-well waveguide-type depleted optical thyristor using the vertical window. The measured switching voltage and current are 3.36 V and 10 μ A , respectively. The lasing threshold current is 131 mA at 25 ° C . The output peak wavelength is 1570 nm at a bias current of 1.22 I th and there is no input signal. The vertically injected depleted optical thyristor shows very good isolation between input and output signals.
