TX/RX subcomponent testing engineer

Job Title
TX/RX subcomponent testing engineer
Job Description
Avicena is a privately held company developing microLED based ultra-low power high bandwidth interconnects for chip-to-chip communications. This technology will revolutionize High-Performance (HPC) and Cloud computing, as well as other industries where low power interconnects are critical like camera sensors, autonomous vehicles, and aerospace. Avicena is headquartered in Sunnyvale, California with a development center in Edinburgh, Scotland. The company was founded in 2019 by leading technologists from the optical networking industry with a track record of delivering breakthrough products. (www.avicena.tech)
Responsibilities

• Characterization of subcomponents of optical transmitters, optical receivers used in parallel opto-electronic interfaces (Light emitting diodes (LEDs) and Photodetectors (PDs))
• Work with the epitaxial development group to characterize the bandgap structure of LEDs, modulation speed, efficiency using various methods (spectroscopy, S21 measurement, SIMS, FIB, SEM, etc..)
• Test photo detectors and extract the relevant parameters and provide feedback for the PD developers.
• Maintain and improve opto-electronic test systems for full characterization of optical sub-components and modules.
• Run link DOEs for sub-component development.

Qualifications

• MS or PhD in electrical engineering or physics with 2+ years of experience
• Understanding of solid-state physics and physical principles behind LEDs PDs design and critical parameters of the transceiver system design based on LEDs and PDs.
• Experience with LED/PD characterization
• Understanding of Optics

Preferred Qualifications

• Being able to execute DOEs, targeted to improve the performance of sub-components. Provide clear/ concise data summary and conclusions
• Strong verbal and written communication skills
• Working knowledge of high-speed test instruments such as VNAs, sampling and real time oscilloscopes and spectrum analyzers, optical spectrometers
• Hands-on lab experience especially with probed/free space coupled (using stages) optical systems
