Titel
Ultra-low threshold 1490 nm surface-emitting BH-DFB laser diode with integrated monitor photodiode
Abstract
1490nm surface emitting BH-DFB-laser diodes incorporating a 45° turning mirror and an integrated monitor photodiode are presented for the first time. The devices show VCSEL-like threshold currents of as low as 3...7mA in the operation temperature range between 20°C and 90°C and a modulation bandwidth of >8GHz. The integrated monitor diode operates temperature independent and is therefore well suited for laser power control.
