Reconfigurable broadband photonic characterization system

We propose to establish an optical characterization system of photonic devices, covering continuously the O, E, S, C, L bands from 1260 to 1630 nm. The resources enabled by this system will be distributed over a reconfigurable fiber-optic network to eight laboratories in the Center for Optics, Photonics and Lasers. Spectral characterization of optical components and photonic integrated circuits is essential for our research program on next-generation optical communications technologies, which requires high-performance fast-swept lasers and flexible detection configurations over an ultrabroad spectral range. We examine these devices and their applications for various applications such as data center interconnects, metro and long-haul communications, radio-over-fibers for next-generation wireless communications, and chip-scale sensors.
