The Luxmux Low DoP Integrated Spectral Bench is a depolarized broadband optical source. The G1 (Single SLED) and G2 (Multi-SLED) series come in a range of power levels and spectral coverages. The ISB is designed as a compact and integrated light source unit. The ISB sources are extraordinarily robust and reliable, built for intensive use, and can replace multiple single SLED sources. DoP is an important property of light sources, as it directly relates to the accuracy of optical component characterization, the sensitivity of sensor systems, and the quality of optical signals in optical communication systems.

Our light sources are presented in an optical platform, optimized for cost-effective development and manufacturing of optical spectral combining. Our systems are designed to help manage an industry’s test and measurement needs that require flexibility and dynamic performance. We aim to offer researchers, designers, and manufacturing engineers a broadband solution with the broadest singular spectrum range of > 400 nm for Low DoP characteristics of SLED photonic light sources.

Luxmux’s low DoP solutions are relevant to applications that require a stable and accurate DoP as a reference light source for system monitoring and quality assurance. Low DoP light source measurements require different capabilities and limitations. Luxmux offers multiple spectrum configurations and operational capabilities to suit the requirements of various applications. Luxmux provides a wide variety of Superluminescent Light Emitting Diodes (SLED) for the Near Infrared Range (NIR) at different wavelengths ranging from 1265nm to 1725nm, with different output power and bandwidth values. It exhibits excellent wavelength stability, high power, low-intensity noise, low coherence, and significantly large bandwidth.

KEY CAPABILITIES:

The ISB (Integrated Spectral Bench) exhibits excellent wavelength stability, high power, low-intensity noise, low coherence, and significantly large bandwidth. The Luxmux Low DoP series of all-semiconductor optical sources has a wide selection of wavelengths that can be offered singularly or combined, covering the entire range of telecom spectral bands (O to U). The CW output standard model provides excellent stability in output power and spectrum and a driver circuit to provide overlapping spectral coverage from up to six individual light sources. This user-controlled chassis offers complete control of all light sources enclosed. The ISB systems come with USB, RS-232, and Ethernet communication ports for an easy, flexible interface with computers and other instruments. It is an ideal source for OCT, fiber sensors, fiber gyros, PM patch cord extinction ratio (ER) measurement, and general-purpose test and measurement.

FUNCTIONAL DESCRIPTION

G1 and G2 Series Options:

• Low-Degree of Polarization (DoP): the ISB provides under 10 percent DoP across the entire 1265nm – 1725nm range. This minimizes polarization sensitivity of fiber sensors and reduces the effects of polarization-dependent loss
• Free Space: This selection results in a direct laser beam for higher-power applications that do not require fiber optics.
• Power Meter: an integrated InGaAs Power Meter can be added to ISB models upon customer request. The power meter adapters can come with FC/APC, FC/PC, or SMA connector.
