[Back ground]

In recent years, an explosive increase of data traffic volume in the communication line is progressing on a global scale. Between 2017 and 2025, the demand for 100 G / 400 G / 800 G optical transmission in data centers is expected, and the 5th generation base station deployment for mobile progresses. Therefore, the optical communication market is expected to expand more and more in the future.
Renesas mass-produces cutting edge semiconductor lasers (LDs) and photodiodes (PDs), which are key devices for large capacity and high speed optical fiber communication, based on our own core competence technologies. We are looking for engineers involved in designing and evaluating high-speed optical devices or process development of compound semiconductors to strengthen the competitiveness of Renesas LD/PD and to accelerate the development of next-generation devices.



Chip development of semiconductor laser / photodiode for optical communication

  • Design and simulation of high-speed optical devices (optical waveguide, static characteristics, dynamic characteristics, etc.)
  • Process development of compound semiconductors (crystal growth, electrode formation, chip formation, etc.)
  • Evaluation and analysis of static characteristics (electric / optical characteristics), dynamic characteristics (modulation characteristics), reliability for developed products
  • Mass production of developed products (test yield analysis, process defect reduction)
  • Customer response (technical support in design-in activities, etc.)


[Required Skills and Work Experience]


  • Experience and knowledge on semiconductors and processes
  • Communication and negotiation skills with relevant departments
  • Person who can positively and voluntarily respond to issues
  • Person who can flexibly respond and challenge to environment change


  •  Experience and knowledge on compound semiconductors and processes
  • Development experience or knowledge of semiconductor laser, photodiode, or high frequency device
