Multidimensional subwavelength position sensing using a semiconductor laser with optical feedback

Abstract

We demonstrate experimentally how to harness quasi-periodic dynamics in a semiconductor laser with dual optical feedback for measuring subwavelength changes in each arm of the cavity simultaneously. We exploit the multifrequency spectrum of quasi-periodic dynamics and show that independent frequency shifts are mapped uniquely to two-dimensional displacements of the arms in the external cavity. Considering a laser diode operating at telecommunication wavelength λ1550nm, we achieve an average nanoscale resolution of approximately 9.8 nm (λ/160).
