Integrated Photonics : Small, fast, good and cheap?

Shayan Mookherjea


Integrated photonics can be used not only to reduce the size, weight and power (SWaP) of optical assemblies, but also improve functionality, and achieve record levels of performance in some cases. But what is the cost, and how long does it take to realize a concept?


I will present examples of my group’s research in these areas of silicon photonics, in which we hold currently hold the records:

  • Optical filters: upto 235 coupled silicon microrings; upto 100 dB contrast
  • 100 GHz bandwidth modulators in hybrid silicon – lithium-niobate
  • Efficient low-pump-power wavelength conversion in silicon photonics
  • 31 and 1.55 um entangled photon-pair generation using silicon photonics
