Abstract

The operation principle and fabrication process of the tunable twin-guide (TTG) DFB laser diode are presented. The TTG-DFB laser is a novel single-frequency tunable laser which needs only a single control current for a wide continuous tuning range. Very low cw threshold currents of 12-18 mA at room temperature, spectral linewidths as low as 20-30 MHz, and a continuous tuning range of 1.5 nm at a tuning current of 60 mA are obtained with first, still non-optimised devices. The threshold current and spectral linewidth vary only slightly over the entire tuning range.
