Description
Summary:We propose and demonstrate a low-cost integrated photonic chip fabricated in a SOI foundry capable of simultaneously routing and amplifying light in a chip. This device is able to compensate insertion losses in photonic routers. It consists of standard Si/SiO2 ring resonators with Er:Al2O3 as the upper cladding layer, employed using only one simple post-processing step. This resulted in a measured on/off gain of 0.9 dB, with a footprint smaller than 0.002 mm2, and expected bit rates as high as 40Gb/s based on the resonance quality-factor. We show that the on/off gain value can be further increased using coupled rings to reach net gain values of 4 dB.
