ABSTRACT
InGaAs/GaAs multiple quantum well (MQW)-depleted optical thyristor lasers operating at 1.06 µm with a waveguide-type PiNiN structure is presented for the first time. The optical thyristor lasers clearly show nonlinear S-shaped current-voltage and lasing characteristics. The measured switching voltage and current are 5 V and 1 mA, respectively. The holding voltage and current are 2.6 V and 3.6 mA, respectively. A relatively high output light power of 30 mW per facet at room temperature is achieved. The lasing wavelength is 1.055 µm at a bias current of 80 mA at 25 °C.
