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
