[交流] 【CSC博士招生】埃因霍温理工大学（TU/e）：窄线宽高功率可调激光器

Advanced integrated tunable laser with narrow linewidth and high power

There is an increasing demand for narrow linewidth and wavelength tunable lasers for e.g. applications in telecommunication, metrology applications such as high resolution Fibre Bragg Grating sensor systems, laser imaging systems and microwave photonics. In these applications often multiple lasers are required and the lasers need to be combined with other optical circuitry. For this reason there is an interest in realizing such lasers on a single photonic integrated circuit, a single chip, which not only allows for the efficient fabrication of larger number of devices and more robust operation, but also opens up alternative technical solutions such as the close integration of electronics.

This realization of stable tunable lasers using photonic integration brings specific technological challenges. The boundary conditions on the laser design can be very different from devices made from individual components. In this project we want to investigate the realization of tunable and narrow linewidth single mode lasers in photonic integration platforms (InP and SiN). The major research aspects include:

-Cavity design to alleviate degradation induced by nonlinearity, dispersion and loss based on ring filters and low loss waveguide couplers inside laser cavity;

-High output power enabled by mode field optimization and novel active layer;

-Topological protection induced single mode lasing with narrow linewidth

-Broadband directly-modulated laser with narrow linewidth
