DOI: 10.1109/tim.2023.3251409

Abstract: Commercialization and industrial deployment of optical feedback interferometry or self-mixing interferometry (SMI)-based displacement instruments are held back due to inaccurate fringe detection under different optical feedback or speckle induced by operating conditions. In this work,… read more here.

DOI: 10.1364/ao.57.004067

Abstract: Specular reflection from the surface of targets or prepared specimens represents a significant problem in optical microscopy and related optical imaging techniques as usually the surface reflection does not contribute to the desired signal. Solutions… read more here.

DOI: 10.1364/oe.550127

Abstract: Robust operation of optical feedback interferometry-based instruments requires controlling the amount of light that is reflected back into the laser. To this end, here we propose an on-chip optical feedback interferometry system with an integrated… read more here.

DOI: 10.1364/ol.44.000903

Abstract: We demonstrate a nanometric sensor based on feedback interferometry in a distributed feedback (DFB) laser by using a measurement of either the optical frequency or laser voltage. We find that in an optimal range of… read more here.
