Senior Principal Engineer (Laser Development)

Denselight Semiconductors Pte Ltd

Denselight Semiconductors Pte Ltd company logo

Job Objectives


Design and develop both optoelectronics devices and integrated photonics sub-system platforms. Devices includes but not limited to SOA, gain chips, FP lasers, DFB lasers (CW and DML) and SLEDs. Photonics integrated platforms include but not limited to photonics integrated circuits, Silicon-based integrated platforms, standard/custom packaged modules, as well as optoelectronics sub-systems (i.e. includes both optical and electronics sub-modules) to meet design goals and requirements.


Duties and Responsibilities

  • Perform simulation of optoelectronic devices (CrossLight, ALDS, Optiwave), optical ray tracing (Zemax, Optalix), thermal (Solidworks) and electrical (5Spice) properties of optoelectronics devices
  • Analysis of optoelectronics device epi growth, participate in wafer fabrication process integration, mask design integration, device functionality and reliability performance characterization and test results.
  • With reference to state-of-art competitors, simulated performance and data-mining internal test-results database, you will refine the design, fabrication specifications, and simulation model and parameters to optimize fit between design and measured outcomes.
  • Report generation of design and simulation outcome with support of experimental data, where available
  • Build up database of optoelectronics device design white papers, and management of all design documentation repository
  • Responsible for leading/co-leading programs with several major global players in the development of photonic integration solutions to support the Silicon Photonics platform for datacom and sensing applications.
  1. Development will be beyond simplex monolithic integration with regrowth for spot size converters and array devices, towards multiple functionality PICs incorporating active devices of lasers, modulators and detectors with passive devices of waveguides, polarizers, MMI splitters and optical filters.
  2. Development of multiple functionality PICs designed to be compatible to Silicon Photonics to form a larger scale integrated System-on-a-Chip component.
  • Lead and manage qualification and transfer of product to manufacturing upon development completion.
  • All other reasonable duties, as assigned


Qualification Guidelines

Minimum Education

Masters (in semiconductor based light emitting optoelectronics preferred)


Minimum Experience

Minimum 10 years’ working experience with technical background in optoelectronics and wafer fab processes in optical laser component, photonics device system and sub-system

Proven working experience in optoelectronics design and development and program/project management in the photonics manufacturing industry
