Sensing platform based on micro-ring resonator and on-chip reference sensors in SOI

This article presents work on a Silicon-On-Insulator (SOI) compact sensing platform based on Micro Ring Resonators (MRRs). In order to enable correction for variations in environmental conditions (temperature, mechanical stress etc), a study has been performed on the performance of uncoated sensing MRRs, and of SU8- and SiO2-covered reference...

An on-chip three-port interferometer for metrology and Fiber Bragg Grating interrogation

Three-port interferometer in silicon-on-insulator for wavelength monitoring and displacement measurement

The wavelength of a narrow-band optical signal can be accurately tracked by means of an interferometer having a fixed path length difference. For example, a low-cost Fiber Bragg Grating (FBG) interrogation system which tracks the FBG reflection wavelength over time can be based on such an interferometer. Alternatively, an interferometer is...

Silicon on insulator photonic integrated sensors: On-chip sensing and interrogation

In this paper, we present two examples of photonic sensors based on ring resonators in Silicon-on-Insulator (SOI) waveguide technology as mass production compatible sensing units for the measurement of: strain, and ultrasound. Furthermore, the sensing units are characterized in extreme conditions to validate their robustness in harsh industrial...

Integrated 3x3 Interferometer

The interferometer based on the fiber 3x3 coupler is already a well-known device for measuring displacements and wavelength shifts. TNO is currently working on the fabrication of an integrated version of this versatile interferometer on Silicon-On-Insulator. The integrated interferometer is expected to be far more stable then the fiber version,...

Low-cost packaging concepts for integrated nanophotonics

Coupling an optical chip to its surroundings is very hard compared to an electrical chip. This complexity is mainly caused by alignment and accuracy challenges and is driving the cost price up to levels at which the commercial benefits of optical chips are no longer obvious, despite their many great technological advantages. Up to 80% of an...
