Abstract

The authors report the detailed characterisation of a widely tunable laser and module that offers the elusive combination of very fast (nanosecond) tuning and narrow linewidth. The laser is fabricated on an active-passive InP-based platform and packaged into a 14-pin butterfly module. Electro-optic tuning is used with reversevoltage bias of tuning sections allowing mA-order dark currents and facilitating nanosecond switching speeds with low power dissipation. The device is suitable for integration into fiber coupled modules such as the nanoiTLA or can be monolithically integrated with other components in a III-V PIC. It is a promising new laser for applications that require fast and wide tuning with low linewidth, such as FMCW (Frequency-Modulated Continuous-Wave) LiDAR and coherent optical packet or burst switching.
