Responsibilities:
- Lead a team of engineers to characterize optical transmitters, optical receivers and link performance of highly parallel opto-electronic interfaces.
- Develop and maintain optical transmission system testing bed for full characterization of optical components and modules as well as system performance measurements.
- Define and run link DOEs using uLED on ASIC transmitters, fiber bundle as transmission and PD on ASIC as receivers.
- Characterize various aspects of both existing and potential future optical components such as evaluating signal-to-noise ratio (SNR), receiver sensitivity, bit-error-rate (BER), crosstalk, power consumptions and link budget of the transmission system
- Work with PCBA design engineers to design, fabricate and bring up test boards. Experience in schematic capture, circuit simulation and PCB design guidanceÂ
Qualifications:
- MS or PhD in electrical engineering or physics with 3+ years of experience
- Expertise with optical transceiver circuits such as Trans-impedance Amplifier (TIA), laser/led drivers and photodetectors
- Familiarity with datacenter class optical module designs for Quad Small Form-factor Pluggable Octal Small Form Factor Pluggable (QSFP)/(OSFP) form factor pluggable modules or emerging Near-Packaged Optics (NPO) or Co-Packaged Optics (CPO) approaches.
- Experience with optical transceiver test methodologies
- Familiarity with industry standards including IEEE Ethernet standards, OIF standards and MSAs
Preferrred Qualifications:
- Ability to work cross-functionally with ASIC, packaging and optical design teams and provide clear technical inputs
- Strong verbal and written communication skills, and ability to articulate and engage with both technical and non-technical stakeholders at all levels
- Ability to code scripts in python for validation and data analysisÂ
- Working knowledge of high-speed test instruments such as VNAs, sampling and real time oscilloscopes and spectrum analyzers
- Hands-on lab experience especially with probed/free space coupled (using stages) optical systems
