摘要: PURPOSE: To apply a common electric potential for controlling an active layer and turning layers through a substrate in a TTG-DFB type laser diode which is equipped with a layer structure constituted of the active layer, intermediate layer, and tuning layers on the substrate.收藏...
In 2012 we have demonstrated a simple kHz-linewidth laser just splicing a standard distributed feedback (DFB) laser diode and a few passive telecommunication components. The principle of operation employs the mechanism of self-injection locking that significantly improves DFB laser performance. While a...

We present a detailed investigation for realizing sub-mm long on-chip laser structures operating at λ = 1.533 µm on the silicon-on-insulator photonic platform by combining a multi-segment silicon waveguide structure and a recently demonstrated erbium-doped thin film deposition technology. ...
The DCFS first provides optical self-injection feedback to compress the laser linewidth, and then the two feedback lengths are carefully optimized to achieve SLM output via the Vernier principle and the suppression of modes overlapping between two cavities. The linewidthes of 1 MHz and 200 ...
