Advanced photonics on-wafer testing system delivers automated alignment, simultaneous optical-optical and optical-electrical device tests

An advanced photonics on-wafer testing solution delivers industry-first capabilities including automated alignment, simultaneous optical-optical and optical-electrical device tests.

The joint solution — offered by CompoundTek and developed by that company in cooperation with Keysight Technologies Inc., and FormFactor, Inc. — includes:

The

FormFactor CM300xi-SiPh, with automated wafer-level photonics positioning combined with Keysight’s industry-standard IL/PDL engines and N7700A Photonics Application Suite (PAS), to support wavelength repeatability of ±1.5 pm at two-way sweeps up to 200 nm/sec within 1,240 nm to 1,650 nm to ensure accuracy and repeatability from O-band to L-band.
Keysight’s N4373E 67 GHz Lightwave Component Analyzer which delivers high bandwidth for both optical receiver testing and optical transmitter testing with guaranteed specifications for electro-optical S-parameter measurements for device traceability.
Keysight’s PathWave software platform which provides a consistent user experience, common data formats, and control interfaces.
FormFactor’s SiPh software that enables automated calibrations and alignments and simplifies integration with Keysight’s PathWave software platform, as well as optical instrumentation, to ensure ease of use.

Silicon photonics also delivers benefits for industrial segments such as intra data center communication and data center interconnects (DCI), telecom, 5G and automotive connectivity, high-performance computing, light detection and ranging (lidar), as well as sensing and medical applications.

“Innovation in optics is critical to connect the world and help the industry to monetize 5G, as well as data center and telecom services,” said Dr. Joachim Peerlings, vice president of Network and Data Center Solutions at Keysight Technologies. “Advancing in speed as well as power and cost efficiency requires a tightly connected eco-system to jointly solve the challenges ahead. We are pleased with our partnerships and progress of enabling this eco-system through our unmatched photonics test expertise.”

CompoundTek plans to establish a state-of-the-art silicon photonics testing services hub in Singapore. The company’s chief operating officer, K.S. Ang, commented, “On-wafer level, automated Si photonics optical/electrical/RF testing will help avoid module packaging-level testing turn-around time losses. This test solution complements our current services in mass production volume with fast cycle-time, offered alongside world-class commercial foundry capabilities that accelerate time-to-market to achieve customers’ commercialization goals.”

“FormFactor’s industry-leading silicon photonics wafer test capability allows our customers to obtain repeatable, consistent results with unsurpassed throughput,” said Claus Dietrich, vice president and general manager of the Systems Business Unit at FormFactor. “The system’s automated and high-speed calibration and optical alignment, as well as precision measurement capability in collaboration with Keysight, enable CompoundTek to offer customers faster time to market.”
