A system for determining characteristics of milk or other fluid flowing through an inline sensor system includes a laser engine comprising that emits a laser radiation through the milk as the milk flows through the sensing system, a laser detector that receives the laser after the laser has passed through the milk and generates corresponding laser-readings, one or more processors, and computer memory storing computer-readable instructions. The instructions cause the processors to receive, from the laser detector, laser-readings from the laser detector, identify spectral data reflective of physical properties of the fluid as the fluid flows through the sensing system from the laser-readings, and determine one or more fluid-measures for corresponding one or more constituents of the fluid using the spectra-data and reference-data defining one or more reference spectra for each possible constituent of the fluid.

Solid-state optical devices (10) enable tuning of an electrically tunable depletion region (200) to reduce and block lateral (in-junction) carrier spreading. This capability reduces the negative effects of gain-guiding in the junction plane and reduces an astigmatism of an emitted light beam. The tunable depletion region is created by forming a highly resistive Schottky contact (105, 110) or metal-insulator-semiconductor (MIS) structure (205, 210) next to a waveguide (optical mode propagation) and current injection region (215), where lateral spread due to diffusion is expected. The depletion region area is tuned by applying a bias to the highly resistive Schottky contact or the MIS contact structure. Such contacts or similar lossy structures reduce in-junction plane gain-guiding also when unbiased by creating additional optical loss for the mode, thus reducing the effective carrier density participating in light generation, thereby reducing astigmatism.

Techniques for acquiring and processing data in combination with a photonic sensor system-on-a-chip (SoC) (1) to provide real-time calibrated concentration levels of an analyte (e.g., a constituent molecule within a biological substance) are described. A raw signal (1300) to be analyzed is collected by the sensor chip (1) via diffuse reflectance or transmittance. Determination of the analyte concentration is based on, in part, Beer-Lambert principles and facilitated by applying (2240) scattering correction to the raw signal (1300) prior to decomposition and analysis thereof.

Solid-state optical devices (10) enable tuning of an electrically tunable depletion region (200) to reduce and block lateral (in-junction) carrier spreading. This capability reduces the negative effects of gain-guiding in the junction plane and reduces an astigmatism of an emitted light beam. The tunable depletion region is created by forming a highly resistive Schott ky contact (105, 110) or metal-insulator-semiconductor (MIS) structure (205, 210) next to a waveguide (optical mode propagation) and current injection region (215), where lateral spread due to diffusion is expected. The depletion region area is tuned by applying a bias to the highly resistive Schottky contact or the MIS contact structure. Such contacts or similar lossy structures reduce in-junction plane gain- guiding also when unbiased by creating additional optical loss for the mode, thus reducing the effective carrier density participating in light generation, thereby reducing astigmatism.

Methods for wavelength determination of widely tunable lasers and systems thereof may be implemented with solid-state laser based photonic systems based on photonic integrated circuit technology as well as discrete table top systems such as widely-tunable external cavity lasers and systems. The methods allow integrated wavelength control enabling immediate system wavelength calibration without the need for external wavelength monitoring instruments. Wavelength determination is achieved using a monolithic solid-state based optical cavity with a well-defined transmission or reflection function acting as a wavelength etalon. The solid-state etalon may be used with a wavelength shift tracking component, e.g., a non-balanced interferometer, to calibrate the entire laser emission tuning curve within one wavelength sweep. The method is particularly useful for integrated photonic systems based on Vernier-filter mechanism where the starting wavelength is not known a-priori, or for compact widely tunable external cavity lasers eliminating the need for calibration of wavelength via external instruments.

A layer structure and method of fabrication of a semiconductor heterostructure containing a two-dimensional electron gas (2DEG), two-dimensional hole gas (2DHG), or a two-dimensional electron/hole gas (2DEHG). The heterostructure contains a quantum well layer with 2DEG, 2DHG, or 2DEHG embedded between two doped charge reservoir layers and at least two remote charge reservoir layers. Such scheme allows reducing the number of scattering ions in the proximity of the quantum well as well a possibility for a symmetric potential for the electron or hole wavefunction in the quantum well, leading to significant improvement in carrier mobility in a broad range of 2DEG or 2DHG concentration in the quantum well. Embodiments of the invention may be applied to the fabrication of galvano-magnetic sensors, HEMT, pHEMT, and MESFET devices.
