Development of an automatic bias control for PIC BPSK modulators

Starting date

2 August 2021

Duration of contract

6 months


bis Entgeltgruppe TVöD 5

Type of employment


For optical phase shift keying like BPSK modulation, a closed loop control is necessary to keep the modulator in its working point. The task of this master thesis is the design of an automatic bias control for BPSK modulation on photonic integrated circuits.

  • Literature research on possible algorithms
  • Analytical control design
  • Simulation of the control system in Matlab or similar
  • Implementation on CPU and/or on FPGA in VHDL
  • Assembly of the necessary hardware
  • Experimental evaluation of the BIAS control with bulk and PIC modulators

Your qualifications:

  • experience with control theory
  • experience in optical fibre communications
  • programming in Matlab / Python
  • experience in VHDL

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalleled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (f/m/x). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
