Scientist (Photonics), Thin-Film Lithium Niobate Modulators at A*STAR IME
Job Description
A*STAR’s Institute of Microelectronics (IME) is hiring a Scientist in its Silicon Photonics Department to design high-speed thin-film lithium niobate (TFLN) modulators for next-generation communications up to 400 G per lane. The work includes RF electrode modelling, co-design with driver electronics and packaging, and layout rules for 8- and 12-inch wafer platforms using IME’s industry-grade fabs.

- Posted: 22 April 2026
- Apply: open until filled (re-checked 14 October 2026)
What the post involves
- Design high-speed TFLN modulators for up to 400 G/lane
- Model RF electrodes: impedance and velocity matching and microwave loss
- Optimise modulators with driver-IC and packaging teams
- Define layout and design rules for 8- and 12-inch wafers with PDK-level repeatability
- Analyse data and publish
Why this post matters
Thin-film lithium niobate modulators are among the fastest, most efficient ways to put data onto light, and they are key to future data-centre links. IME is one of few places that can make them on industry-scale wafers, so designs here can move toward products.
What A*STAR is looking for
- A Ph.D. in integrated photonics, optoelectronics, physics or electrical engineering
- A proven record in high-speed electro-optic modulator design
- Proficiency with Lumerical and RF tools such as HFSS or ADS
Nice to have
- Deep TFLN (LNOI) platform knowledge
- Experience interfacing with driver circuits in ADS or Cadence
