1550 nm Tunable VCSEL in TOSA Package with TEC

Lasers based on the innovative High Contrast Grating (HCG) single mode 1550 nm VCSEL.



Bandwidth10’s BW10-1550-T-T7 is part of a family of lasers based on the innovative High Contrast Grating (HCG) single mode 1550 nm VCSEL.

Using the HCG as a tunable mirror leads to a wafer-scale, low cost fabrication process with simple voltage-controlled wavelength tuning for various applications.

The HCG VCSEL is co-packaged with a thermo electric cooler for wavelength stabilization in a 7 pin TO56 package. It offers modulation speeds up to 10 Gbps and a typical tuning range of 10 nm. The TOSA is available for several bands through the C- and L- band.
