Compact silicon photonic wavelength-tunable laser diode with ultra-wide wavelength tuning range 
Date: Mar 17, 2015
We present a wavelength-tunable laser diode with a 99-nm-wide wavelength tuning range.
It has a compact wavelength-tunable filter with high wavelength selectivity fabricated using silicon photonics technology. The silicon photonic wavelength-tunable filter with wide wavelength tuning range was realized using two ring resonators and an asymmetric Mach-Zehnder interferometer.
The wavelength-tunable laser diode fabricated by butt-joining a silicon photonic filter and semiconductor optical amplifier shows stable single-mode operation over a wide wavelength range.
