An optical sensing module suitable for wearable devices, the optical sensing module comprising: a silicon or silicon nitride transmitter photonic integrated circuit (PIC), the transmitter PIC comprising: a plurality of lasers, each laser of the plurality of lasers operating at a wavelength that is different from the wavelength of the others; an optical manipulation region, the optical manipulation region comprising one or more of: an optical modulator, optical multiplexer (MUX); and additional optical manipulation elements; and one or more optical outputs for light originating from the plurality of lasers.

Optical sensing module

A wearable device. In some embodiments, the wearable device includes: a sensing module; and a strap attached to the sensing module, the wearable device being configured to be worn by a user, with a lower surface of the sensing module in contact with the user, the strap extending over an upper surface of the sensing module.

Wearable device

The invention refers to a frequency shifter for heterodyne interferometry measurements, comprising a chip, an input waveguide configured to guide a light beam, at least four phase modulators, each being arranged to receive the light beam from the input waveguide and configured to modulate a phase of the light beam, an output combiner being arranged to let the light beams modulated by each phase modulator interfere, a first output waveguide coupled to the output combiner and configured to receive the modulated light beams constructively interfering at the output combiner, a second output waveguide coupled to the output combiner and configured to receive the modulated light beams destructively interfering at the output combiner, wherein the input waveguide, the phase modulators, the output combiner, the first output waveguide and the second output waveguide are arranged on the chip.

Frequency shifter for heterodyne interferometry measurements and device for heterodyne interferometry measurements having such a frequency shifter

The invention refers to an optical device for heterodyne interferometry, comprising a chip, a beam splitter, a first waveguide arranged on the chip, light propagating in the first waveguide being guided to the beam splitter, a second waveguide arranged on the chip, light propagating in the second waveguide being guided to and/or from the beam splitter, wherein the beam splitter, the first waveguide, and the second waveguide form part of a Michelson interferometer, wherein the first waveguide and the second waveguide at least partially form two arms of the Michelson interferometer, and wherein two further arms of the Michelson interferometer are at least partially arranged outside the chip.

Optical device for heterodyne interferometry

An optical instrument for determining a wavelength of light generated by a light source. The optical instrument may include a signal generator for generating a driving signal, a tunable optical filter device configured to receive the driving signal, the tunable optical filter device configured to diffract the light generated by the light source based on the driving signal, an optical detector device configured to detect a timing of maximum diffraction of light diffracted by the tunable optical filter device, and an analyzer configured to determine the wavelength of the light based the timing of maximum diffraction.
