SUPERLUM is a pioneer on the Photonics market and for over 25 years SUPERLUM has been delivering the most Innovative, Top-of-the-Range Low Coherent Light Emitting Diodes to the World.

SUPERLUM collaborates with leading research groups in developing cutting-edge high performance products and new solutions for Medical OCT and imaging for Life Sciences, Industrial OCT and high precision industrial sensors, Navigation and Aerospace, Metrology and Atomic Microscopy.

Our product portfolio has the widest range of Superluminescent Light Emitting Diodes (SLED or SLD) and Semiconductor Optical Amplifiers (SOA), driving electronics and complete broadband light sources in benchtop and OEM solutions and many more customized products.


SUPERLUM offers a wide variety of low coherent light sources covering spectral band from 660 to 1620 nm, including ultra-high power (up to 100 mW) and ultra-broadband (up to 300 nm)


Superluminescent Light Emitting Diodes are low coherent light sources. SUPERLUM covers the range of 650 to 1620 nm.

Fiber Pigtailed (SM, PM, MM) in DBUT, DIL, miniBUT packages


Semiconductor Optical Amplifiers are optical amplifiers based on a semiconductor gain media.

SUPERLUM offers Fiber-Coupled SOAs at 785, 800, 840, 870, 930 and 1060 nm with gain bandwidth of up to 75 nm and fiber-to-fiber gain of up to 25dB.



SLDs are extremely sensitive to surges and spikes of driving current and require specialized driver and temperature controller to ensure safe and stable operation.

SLD Light Source Modules

Superlum SLD Light Source Modules have an SLD of your choice with a high-precision current driver and temperature controller in one box with an option of modulation (ON/OFF) at up to 50 kHz. Also available with an integrated optical isolator.

Broadband Light Sources

For a wider spectrum we offer Benchtop Low Coherent Broadband Light Sources where 2, 3 or 4 spectrally shifted single mode SLDs are combined to provide a 3dB spectrum width of up to 300 nm. An integrated optical isolator is optional. Remote control through USB or by TTL.


OEM Broadband Light Sources

OEM version of our popular benchtop device. An integrated optical isolator is optional. Remote control through USB or by TTL. Perfect for integration in your own system.

BLL: our new OEM Light Source


Our new BLL OEM Ultra-Compact SLD Light Source features ultra-compact design of 45x60x21.5 mm and is designed for integration onto PCB boards. An optional Evaluation Board allows for a quick and easy BLL light Source setup and testing. The BLL is compatible with most of the SUPERLUM SLDs.

Customized Solutions

SUPERLUM R&D team is open to all suggestions and new ideas for development of new products, and for modification of the existing products.

SUPERLUM is committed to innovative approaches, and to delivering excellence to your project, whether big or small, commercial or academic.


High precision OCT systems (Ophthalmology and other Medical field)

Optical Coherent Tomography (OCT) is a non-invasive, non-destructive imaging technique that enables high-resolution, cross-section imaging of a wide range of highly scattering media, such as biological tissue. It is widely used in Opyjtalmology, SUPERLUM SLD was used in one of the first Ophthalmology OCT systems developed by Prof. James Fujimoto at MIT.Click here to read more

Speckle-free illumination

Full-field imaging applications require increasingly bright speckle-free illumination that can be achieved by using low coherent SLDs instead of conventional thermal light sources with bright light emitting diodes (LEDs) and coherent laser diodes (LD).

High precision OCT systems (Industrial and OCT4NDT)

Industrial OCT is a non-destructive, non-contacting method of control with a micrometers scale resolution without harmful radiation allowing volume orientation, defect detention, 3D visualization, and detection of foreign particles, as well as thickness measurement and surface accuracy.

It includes cost-efficient quality improvement tools for inline inspection of multi-layered objects in manufacturing processes. Click here to read more

Atomic Force Microscopy

AFM) or scanning force microscopy (SFM) is a type of scanning probe microscopy with resolution on the order of fractions of a nanometer, more than 1000 better that the optical diffraction limit

Fiber Optics Sensors and FOG for Aviation and Navigation

A FOG provides extremely precise rotational rate information, in part because of its lack of cross-axis sensitivity to vibration, acceleration, and shock.  High accuracy, compact, potentially low cost FOGs are widely used in aerospace and navigation in stabilization applications.
