Your mission:
Silicon photonics has advanced by lightyears during the past few years, and finally, we have a reliable technology platform (e.g., GF, IMEC) being offered to researchers to try out different circuit design ideas.
 
Light is already a great medium for extremely low-energy computation at extreme speeds. And as the technology progresses, the optical elements will scale in size thus leading to higher density – undoubtedly, this active research community will find breakthroughs to bring them down to the size of 10s of micrometers. Then what would become a challenge is in how to create the supporting analog circuits that are also that size – remarkably, after all the years of development, decent digital-to-analog converters are at a 10x30um size scale (the record MSIC Lab possesses). 
 
In this project, we will explore new architectures both at the optical/electrical side to harness the promises of high bandwidth, and low-energy computation of light-based computing.
Main duties and responsibilities include :
Develop an optical computing hardware including the support silicon circuits and the optical components
  • Study the principles of optical computing elements 
  • Study the charge-domain ADC paradigm
  • Design a silicon photonics chip with light-based analog compute capability
  • (Design an optical thresholding element)
Your profile:
  • Solid background and/or experience in mixed-signal circuit design (this means switched capacitor circuits and not RF) and optics – I know.. these two things are hard to come in one package..
  • Excellent communication/presentation skills in English
  • Excellent knowledge of the following topics:
    • Charge-domain circuits
    • Dynamic amplifiers
    • Analog to digital converters
    • Energy efficiency
    • Optical elements
    • integrated circuits design flow:
      analog design, digital synthesis, layout, place and route…
  • Necessary skills:
    • Fluency in using Cadence Virtuoso Suite
    • Fluency in implementing inference models in Python
    • Fluency in using SPICE simulators (HSPICE, FineSim, AFS, etc.)
    • Fluency in using PCB design suite (Altium)
  • Preferred skills
    • Fluency in running simulations on the Linux terminal 
We offer :
  • A multidisciplinary environment
  • Excellent working conditions
  • Laboratory based in Neuchâtel campus (our building is quite new!)
Preferred start date :
January 1, 2023 +/- 2 months
 
Duration :
For Ph.D: 4 year, will continue with a different project
