EXALOS presents new combined-SLED modules and groundbreaking 488nm Laser Diodes and SLEDs at Photonics West in San Francisco

Combined SLED Modules

EXALOS’s new combined-SLED modules are high-performance, ultra-broadband, fiber-coupled light sources based on superluminescent light emitting diodes (SLEDs). Using an automated, high-precision alignment robot, the output beams of the individual SLEDs are combined using micro-optical lenses and free-space optics to a single, highly polarized output beam that is coupled into a single-mode or polarization-maintaining output fiber. Standard combi-SLEDs are available in the near-infrared, for wavelengths ranging from 750nm to 1600nm, or in the visible range with wavelengths from 650nm to 405nm. The combi-SLED products are highly customizable and meet highest performance and reliability demands.

For the first time, a combination of up to four SLEDs are now integrated into a standard 14-pin butterfly package, achieving, for example, an ultra-broadband output spectrum with a 3dB bandwidth of 165nm at a center wavelength of 830nm, which translates into a coherence length of 2.5 microns in air. At the same time, the optical output has a high output power of 15 mW and a high polarization extinction ratio of more than 20 dB. These combi-SLED sources are also available on a multi-channel driver boards that can be easily integrated into an OEM system, supporting remote operation through a USB interface as well as a digital and analog control interface. Furthermore, these driver boards support fast on-off modulation with rates up to a few 100 kHz.

Features:

  • Compact 14-pin Optical Module
  • Ultra-broad optical spectrum
  • High output power
  • Ultra-low noise (RIN)
  • Multiple spectral ranges
  • Polarization aligned
  • Compact OEM device with drive electronics available

Applications:

  • Optical Coherence Tomography
  • Biomedical Imaging
  • Fiber Sensor Interrogation
  • Component Testing
  • Spectroscopy

EXALOS can offer SLEDs (or LDs) over a wide spectral range from the near-UV (390 nm) to the near-IR (1700 nm). Each combination of SLEDs leads to different optical output power levels of roughly 10mW to 40mW and 3dB Bandwidths of 100nm to 300nm or more. Other combi-SLED modules and micro-optical integrated products can be realized upon request

488nm Laser Diodes and SLEDs

EXALOS has realized a new milestone of its high-performance GaN-based light sources and is introducing high-power 488nm laser diodes in a TO56 package with a free-space output power of more than 50 mW as well as broadband 488nm SLEDs with an ex-fiber output power of more than 3 mW and a 3dB bandwidth of more than 5 nm.

These devices meet highest requirements of low-noise operation, suitable for a wide range of biomedical applications such as fluorescence imaging or flow cytometry. These devices complement the already existing portfolio of GaN-based SLED devices at 405nm, 425nm, 450nm or 510nm with similar performance values.
