Laser written waveguides to the sample edge
Zhi-Kai Pong, Mohan Wang, Ji Qin +2
A method is presented for fabrication of femtosecond laser written waveguides in glass to remove the need for polishing of substrates after processing. It is shown that by amplitud…

Laser-written scalable sapphire integrated photonics platform
Mohan Wang, Patrick S. Salter, Frank P. Payne +3
In this paper, we demonstrate the integration of photonic devices on sapphire substrates using multi-layer depressed cladding waveguides at both 780 nm and 1550 nm. The devices are…
