Abstract :
This paper demonstrates an electro-thermally tunable VCSEL array with an additional tuning electrode. The VCSEL array achieves continuous wavelength tuning of approximately 3 nm with a single-tuning-contact. The deviation in output power is within 1 dB. The power consumption for wavelength tuning is as low as 46 mW. Fast tuning response is expected in the proposed tunable VCSEL because of the small thermal capacity.
