MIP Si-Photonic Variant

The MIP variant for Si-photonic hardware in the loop bridges the gap between algorithmic/architectural exploration and stimulus, and measurement of photonic hardware in the loop of a prototype microsystem. It presents a modular, desktop environment for Si-photonic chip prototyping in a system context.

The platform integrates a PXIe-based control system which includes a system-level design environment, data acquisition, FPGA based signal/control processing, and power supplies, with generic optical source and detection modules and a feedback-controlled optical fibre alignment system.

Benefits

Accelerates research by providing a feature-rich platform for integration and validating of Si-photonic-based microsystems.
Addresses specific research needs through a graphics-based programmable environment and hardware enabling integration of Si-photonic hardware in the loop.
Enables a faster path to commercialization by sourcing commercial-grade components and through compliance with commercial standards and interfaces (e.g., PXI and PXIe).

Applications

A block diagram and photos of this prototype MIP variant are shown below. The photo at the right shows a fibre array aligned to Si-photonic device, with an inset of the resonator transmission spectrum measured using the MIP coupled to an Agilent 81600B tunable source.

Possible research applications include control of Si-photonic-based ring resonators and sensors for biomedical applications, and Micro-Opto-Electro-Mechanical Systems (MOEMS) such as optical gyroscopes or accelerometers, under real-time feedback control.

Features
