    Abstract: A phase difference measurement device comprises at least two optical waveguides arranged in parallel in a first plane. Each optical waveguide comprises a proximal portion and a distal portion. The proximal portion of at least one of the optical waveguides comprises a phase-shifting device configured to induce a phase shift of a light wave being transmitted in the phase difference measurement device. The device further comprises at least one phase interrogator device arranged in the first plane between two neighboring optical waveguides of the optical waveguides. The phase interrogator device is configured to couple light from the two neighboring optical waveguides to interfere in the phase interrogator to generate an interference light wave. At least one photodetector is arranged for detecting the interference light wave. The photodetector is arranged in a second plane other than the first plane.

    Abstract: The present disclosure describes a device for measuring an optical absorption property of a fluid as function of wavelength. The device comprises a broadband light source for emitting light, a plurality of integrated optical waveguides for guiding this light and a light coupler for coupling the emitted light into the integrated optical waveguides such that the light coupled into each integrated optical waveguide has substantially the same spectral distribution. The device also comprises a microfluidic channel for containing the fluid, arranged such as to allow an interaction of the light propagating through each waveguide with the fluid in the microfluidic channel, and a plurality of spectral analysis devices optically coupled to corresponding waveguides—such as to receive the light after interaction with the fluid. The spectral analysis devices are adapted for generating a signal representative of a plurality of spectral components of the light.

    Abstract: A system for determining a range of a scene is provided. In one aspect, the system includes an optical source to generate an input signal and a first optical coupler to tap a predetermined portion of the input signal as a local oscillator signal. The system includes an emitting unit to transmit a remaining portion of the input signal as an output signal onto the scene, and an imaging unit to receive return signals from the scene. The imaging unit includes an array of detectors directly coupled to one or more lenses. A position of each detector is associated with a unique direction of the return signals. Also, the lenses may receive and direct the return signals onto the detectors. Further, each detector of the array is configured to mix the local oscillator signal with a corresponding return signal thereby generating a RF beat signal that is further processed to determine the range of the scene.

    Abstract: Example embodiments relate to an integrated lens-free imaging device. One embodiment includes a lens-free imaging device for imaging a sample. The lens-free imaging device includes a radiation guiding structure that includes a first surface parallel with a second surface. The lens-free imaging device also includes an imaging region. The radiation guiding structure is adapted for receiving an incoming radiation wave, thereby obtaining a confined radiation wave. At least one perturbation is present in the radiation guiding structure for generating, from the confined radiation wave, a first radiation wave and a second radiation wave. The radiation guiding structure is configured to direct the first radiation wave out of the radiation guiding structure toward the first surface to a sample measurement region. The radiation guiding structure is further configured to direct the second radiation wave toward the second surface to the imaging region.
