Nonlinear photonics applications of tellurite-coated silicon nitride waveguides

This project is about integrated photonics. Similar to integrated electronics, both have many applications in our lives such as in communications, biosensing, security, display and imaging. Interestingly, photonic circuits are poised to replace electronics circuits in telecommunications and data centers. Compared to electronics, they will reduce cost, increase speed and bandwidth of the future Internet coping with constant increasing demand that will not be met by the electronics-based systems. Particularly, this project’s goal is to bring bulky top of the table optical systems into a nanoscale integrated photonic chip. Using the novel tellurite glass, on-chip model locked lasers (MLL) and supercontinuum generation (SCG) will be explored. Mode locked laser is a high power pulsed laser that has interesting applications for example in distance measurements, material processing (e.g. micromaching) and laser surgery. Whereas, supercontinuum generation is widening of light spectrum with prospective applications in frequency measurements, fluorescence microscopy, bio-imaging and ultra-precise time keeping.
