Photonic Molecules For Optical Signal Processing

We demonstrate how CMOS compatible photonic molecules (PM) can break the fundamental interdependence among quality factor (Q), channel spacing and size of microring resonators. Different PM architectures are presented for efficient and compact optical signal processing.5455Barea, L.A.M., Vallini, F., De Rezende, G.F.M., Frateschi, N.C., Spectral engineering with cmos compatible soi photonic molecules (2013) IEEE Photonics J., 5 (6), pp. 2202717-2202717Barea, L.A.M., Val Lini, F., Jarschel, P.F., Frateschi, N.C., Silicon technology compatible photonic molecules for compact optical signal processing (2013) Appl.

Low-power Four-channel Wavelength Multicasting In Embedded Microring Resonators

We demonstrate four-channel all-optical wavelength multicasting using only 1 mW of pump power and channel spacing of 40-60 GHz. Our device is based on a compact embedded microring design fabricated on a scalable SOI platform. © 2014 OSA.Bogaerts, W., De Heyn, P., Van Vaerenbergh, T., De Vos, K., Kumar Selvaraja, S., Claes, T., Dumon, P., Baets, R., Silicon microring resonators (2012) Laser Phot.
