Integration of interband cascade photodetector for gas sensing
Integration of interband cascade photodetector for gas sensing
Optical gas sensors have been useful for industries such as mining, medicine as they allow for highly sensitive measurements.
We have developed a methodology to integrate a 12-stage ICIP (interband cascade infrared photodetector) onto an SOI chip of the purpose of achieving an on-chip, laser and detector integrated sensor. We have utilised 8-inch SOI wafers for this structure.
Sensing will exploit absorption spectroscopy and measure the change in output power upon interaction with the target gas. For this design we optimised our waveguides for the minimal loss without cladding to improve interaction between the gas and the mode of the LASER.
These waveguides are designed for three wavelengths, 3.3

Abstract
Optical gas sensors have been useful for industries such as mining, medicine as they allow for highly sensitive measurements.
We have developed a methodology to integrate a 12-stage ICIP (interband cascade infrared photodetector) onto an SOI chip of the purpose of achieving an on-chip, laser and detector integrated sensor. We have utilised 8-inch SOI wafers for this structure.
Sensing will exploit absorption spectroscopy and measure the change in output power upon interaction with the target gas. For this design we optimised our waveguides for the minimal loss without cladding to improve interaction between the gas and the mode of the LASER.
These waveguides are designed for three wavelengths, 3.3
