A silicon chip with integrated laser and optical grating offers new possibilities for telecommunications

(PhysOrg.com) — Silicon is an ideal platform for integrated photonic circuits because the material is cheap and readily available. Silicon chips with an integrated laser source capable of emitting light at a specific wavelength are particularly useful in telecommunications. Unfortunately, silicon is a material with high optical loss, which often degrades the output power and performance of the laser source.
