    Master Student in Electrical Engineering (f/m/x) - Design of a switched current source - Stellenbeschreibung

    Connecticum Job-Nr 1551042

    Course paper / final thesis, Student placement
    Design of a switched current source for the use in power efficient optical amplifiers (EDFAs) in optical communication terminals
    Starting date

    15 October 2022

    Duration of contract

    6 months


    up to the German TVöD 5

    Type of employment


    The optical communication group of DLR’s Institute of Communications and Navigation develops experimental laser communication systems for optical data links between airborne carriers such as airplanes or satellites and optical ground stations. Optical signals are usually amplified by the use of erbium doped fiber amplifiers in order to achieve optical output powers of several Watts. Commercially available driver circuits are mainly based on linear circuits, which results on low efficiency. This is critical for the use in satellites.

    In order to design these amplifiers as power efficient as possible, a switched laser diode current driver should be developed.

    Your tasks will be:

    • circuit design and simulation of switched current source
    • hardware implementation on breadboard level
    • test of circuit on prototype system
    • optimization of circuit with focus of efficiency and current ripple
    • study direction of electrical engineering or similar
    • profound knowledge in analogue circuit design
    • profound knowledge in switched circuit design, such as discrete DCDC converter design
    • basic knowledge about lasers and optical communication

    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.
