Project Description

Multi-purpose optical sensor for gas and bio sensing

Mach-Zehnder interferometer assisted ring resonator sensor (MARC) to generate unique interferometer spectrum along with ring response.

Target applications

  • Gas sensing
  • Bio sensing

Benefits of MARC

  • Large dynamic range, without compromising on sensitivity
  • Unique spectral signatures enabling multiplexing of sensors
  • Versatile sensing applications
  • Low cost, narrow-band tunable laser (thermally controlled) and one/two detector system
  • Low production cost, CMOS compatible
  • Has potential for miniaturization in the order of a matchbox.
