Written By Kris Light

Join AIM Photonics as experts share a selection of the Institute’s recent technology advancements in silicon photonics at the SPIE Photonics West conference Jan. 25-30, 2025 at the Moscone Center in San Francisco, California.

In addition the highlighted talks below, visit AIM Photonics’ exhibit booth (#233), where members of the technical staff will be available throughout the conference for deep-dives on how AIM Photonics can help advance your company’s innovative ideas into manufacturing-ready prototypes using our design enablement, multi-project wafer and electronic-photonic test, assembly and packaging services.

“Photonics West is always an exciting time to connect with colleagues and innovators from across the photonics community,” said Nathan Lin, Director of Photonics Outreach. “We look forward to sharing how the Institute is helping to drive progress in silicon photonics and learning more about the ideas and challenges shaping the future of our industry.”

This year the Institute is collaborating with members exhibiting at the conference. This is a great opportunity to see how working together advances the U.S. integrated photonics ecosystem.

Design Enablement Offering in Emerging Areas in 300 mm Silicon Photonics Technologies: Quantum and Sensors

In contrast to high-volume telecom and datacom applications, this presentation will demonstrate component development and PDK enablement in 300 mm CMOS-compatible silicon photonics technologies developed by AIM Photonics for quantum and sensing applications. Component development using simulations and broadband measurements in AIM Photonics’ sensors PDK targeting 500–1300 nm will be presented, including sub-circuit-based compact models for a suite of ring resonators with air, oxide, and water cladding options that accurately predict the measured characteristics. In addition, application circuits that use features of these technologies and PDKs will also be presented.

Presented by: Amit Dikshit, Design Enablement Manager
Date/Time: Wednesday, January 29 • 6-8 p.m.

Demonstration of a Tunable Add-Drop Filter Developed in AIM Photonics Process Technology

In this presentation, an all-silicon tunable add-drop filter developed in AIM Photonics 300 mm process technology will be demonstrated. The filter includes a 7-µm radius silicon ring waveguide and two silicon straight waveguides outside the ring with a coupling gap of 150 nm. The filter tuning function is achieved by integrating a doped silicon-based resistive heater. The light is coupled to the filter using grating couplers, which couple input and output light. The 3 dB filter bandwidth of a single resonance is about 0.3 nm and can be tuned up to 4 nm by applying 20 mW (6 V) of electrical power to the thermal heater. It is expected that the filter can be tuned over its full free spectral range of 13 nm by applying 20 V to the thermal heater.

A 5 μm Radius Compact Ring Modulator with a Wide Free Spectral Range, Large Extinction Ratio, and High Wavelength Modulation Developed in AIM Photonics’ 300 mm Process Technology

In this presentation, a 5-μm radius compact silicon micro-ring modulator fabricated using AIM Photonics’ 300 mm process technology will be demonstrated. This modulator device includes a single-bus, straight silicon waveguide, and a circular ring made of silicon waveguide. The circular ring has a radius of 5 µm, and a 220-nm thick silicon-on-insulator (SOI) waveguide is used both for the circular ring and the straight waveguides. The modulator performs over a wide spectral range of 20 nm, exhibits a large extinction ratio, and has a high modulation efficiency of about 1.5 nm at 1.0 V.
