ResearchOnsiteInstitute of Microelectronics
Key Responsibilities
- Designer/Scientist for Silicon Photonics Department As part of NSTIC's Silicon Photonics Department, the candidate will be working on the design of high-speed modulators.
- Work closely with an excellent multidisciplinary team involving photonics, semiconductor process, and fab operation to realize next-generation photonic integrated chips using our industry-grade fabrication facilities.
- Design of high-speed thin-film lithium niobate (TFLN) modulators aiming for next-generation communications systems up to 400 G/lane.
- Perform RF modelling of electrodes including impedance matching, velocity matching and microwave loss.
- Co-work with EIC driver design and system packaging team to optimize TFLN modulators and packaging parasitics.
- Drive the layout and design rule definition for 8-inch/12-inch wafer platforms, ensuring designs are robust for PDK-level repeatability.Data analysis and documentation.
Requirements
- PhD in Integrated Photonics, Opto-electronics, Physics, Electrical/Electronic Engineering or equivalent.
- Proven track record in high-speed electro-optic (EO) modulator design.
- Deep understanding of the TFLN material platform (LNOI) is highly preferred.
- Experience in simulation software such as Keysight ADS or Cadence for interfacing with driver circuits is a plus.
- Proficiency in photonics simulation tools (Ansys Lumerical) and RF simulation tools (Ansys HFSS, Keysight ADS) for circuit-level analysis.
- Strong communication and ability to work well in a large team.
