Photonic Components

This was a project under the Thrust 2 “Subsystem Integration and Silicon Nanophotonics” of the NSF-funded Center. The goal of this research was to design, fabricate and test microchip-scale silicon photonic components for optical WDM (wavelength division multiplexed) add/drop functionality in access and data networks. This chip was intended for use in a campus ring network.

Broadband Frequency

We demonstrate an ultra-broadband silicon photonic interleaver capable of interleaving and de-interleaving frequency comb lines over a 125 nm bandwidth in the extended C- and L-bands. We use a ring-assisted asymmetric Mach Zehnder interferometer to achieve a flat-top passband response while maintaining a compact device footprint. The device has a 400 GHz free spectral range to divide an optical frequency comb with 200 GHz channel spacing into two output groups, each with a channel spacing of 400 GHz, yielding a potential capacity of 78 total wavelength-division multiplexed channels between 1525 nm and 1650 nm. This device represents an important step towards realizing highly parallel integrated optical links with broadband frequency comb sources within the silicon photonics platform.

Networking Testbed

The goal of this project was to design silicon photonic components for optical WDM (wavelength division multiplexed) add/drop functionality in access and data networks. One of the key functionalities that was required by the campus networking testbed was to control the optical power levels in the WDM network of each channel without requiring separate components. This was most easily achieved by integrating the Variable Optical Attenuator (VOA) functionality together with the add-drop functionality on the same photonic chips.
