Postdoctoral Associate (Optical Metasurfaces)

Project Overview

Wafer-Scale Integrated Sensing Devices based on Optoelectronic Metasurfaces (WISDOM) focuses on semiconductor wafer growth and processing for photonic applications.

This program aims to pioneer a wafer-scale integrated platform which seamlessly combines metasurface optics, optoelectronic devices with a focus on light emitting diodes (LEDs) and vertical surface emitting laser arrays (VCSELs), and silicon complementary metal-oxide semiconductor (CMOS) electronics.

Researchers from MIT, NUS, NTU, A*STAR, Stanford University and University of Illinois form a uniquely qualified interdisciplinary team possessing the skills and infrastructure needed to perform the proposed research. WISDOM program will also involve a strong network of industry partners which are committed to development and translation of the WISDOM technology, thereby enabling outcomes from the program to make a direct impact on industrial applications.

Responsibilities

The WISDOM IRG at SMART is seeking a qualified candidate for a Postdoctoral Associate position jointly supervised by Prof. Juejun Hu and Prof. Cheng-Wei Qiu. This position will entail the following technical responsibilities:

1. Perform optical modelling and layout for metasurface devices for both in-house fabrication and foundry tape-out.

2. Execute cleanroom processing tasks including (but not limited to): electron beam and photolithography, deposition of dielectric thin films, die bonding, etc. and working with external foundry fabrication service providers.

3. Carry out characterization of metasurface devices, including (but not limited to): optical and electron microscopy, building optical setups, PSF/MTF testing, etc.

4. Coordinate with external foundries on device fabrication and integration.

5. Lead the continual improvement project for wafer-level metasurface integration.

5. Perform other duties as assigned.

Requirements

1. Ph.D. Degree in Electronic/Electrical Engineering, Materials Science, Physics, Mechanical Engineering, or other related discipline.

2. Prior experience in optical metasurface design, fabrication, and testing is preferred.

3. Prior experience in photonic/semiconductor foundry tape-out is preferred.

4. The candidate needs to work well in a team, and with other lab/cleanroom users.

Interested applicants are invited to send in their full CV/resume, cover letter and list of three references (to include reference names and contact information). We regret that only shortlisted candidates will be notified.
