Superluminescent diodes for optical coherence tomography (SD-OCT) - Inphenix https://www.inphenix.com/en/superluminescent-diode-devices/ A superluminescent diodes for optical coherence tomography emits low coherence but high brightness light. #Superluminescentdiode is applied in smooth and high intensity broadband optical spectrum. They don't have built-in optical feedback mechanism. SLD is a #semiconductoropticalamplifier with no input signal, where weak spontaneous emission into the waveguide mode is followed by strong laser amplification.

Custom Gain chip - Inphenix Inc. https://www.inphenix.com/en/gain-chip/ #Gainchip is identical to laser diode chips except that they have a deep anti-reflective coating on one or both facets, which raises or eliminates the threshold of self-lasing. Gain Chip is used as a gain medium for Single FBG Lasers or Externally Tunable Cavity Lasers. Inphenix offers standard gain chip per our datasheet requirements as well as custom gain chip. The broadband gain chip is a #superluminescentdiode that serves as both a broadband light source and a frequency-agile gain medium, is at the heart of the external-cavity laser.

Major Difference Between DFB Laser And DBR Laser https://www.inphenix.com/en/dfb-laser-vs-dbr-laser/ A DFB laser is a type of diode laser that generates resonance and oscillation in the cavity using diffraction gratings rather than mirrors. The laser’s purpose is to sharpen the output of conventional Fabry-Perot lasers. #DBRlasers are among the earliest, if not the first, single frequency lasers ever built. These are tunable single mode diode lasers with a resonator made of a short piece of active fiber sandwiched between two Fiber Bragg Gratings. In comparison to the #DFBlaser, the DBR laser generates single frequency, phase coherent photons at a specific wavelength.

Swept Source Laser at Inphenix Inc. https://www.inphenix.com/en/swept-source-laser/ Inphenix’s swept source laser offers deep penetration, long coherence length and high resolution. Based on Inphenix’s leading #Semiconductor Optical Amplifier (SOA) technology, swept source is specifically designed for #SweptSource Optical Coherence Tomography (SS-OCT) and Optical Frequency Domain Reflectometry (OFDR) applications.

A Superluminescent diode (SLD) at Inphenix Inc https://www.inphenix.com/en/superluminescent-diode-devices/ A #superluminescentdiode is one type of edge-emitting semiconductor light source that emits low coherence but high brightness light. Mainly, Superluminescent diodes are applied in smooth and high intensity broadband optical spectrum. They don't have built-in optical feedback mechanism. #SLD provides amplified spontaneous emission and can be efficiently coupled into a single-mode fibre.

VCSEL (Vertical Cavity Surface Emitting Laser) - Inphenix Inc. https://www.inphenix.com/en/vertical-cavity-surface-emitting-laser-vcsel/ A VCSEL (vertical cavity surface emitting laser) is a surface-emitting #semiconductor light source which emits laser beams in a direction perpendicular to it’s top surface. Individual #VCSEL emitters are very small, typically around 10 microns in diameter, but collectively generate a much higher output power level. Vertical cavity surface emitting lasers (VCSELs) have been used for many different applications like LiDAR Systems, 3D Scanners, Proximity Sensors and Telecommunications.

Semiconductor Optical Amplifier (SOA) - Inphenix Inc. https://www.inphenix.com/en/semiconductor-optical-amplifiers/ A Semiconductor Optical #Amplifier is essentially a laser diode (LD) with no feedback from its input and output ports and hence is also referred to as a Traveling-Wave Amplifier (TWA). Semiconductor optical amplifier (SOAs) have proven to be versatile and multifunctional devices that are key building blocks for optical networks. #SemiconductorOpticalAmplifiers should have the highest gain appropriate to the application. A wide optical bandwidth is also desirable so that the Semiconductor Optical Amplifier (SOA) can amplify a wide range of signal wavelengths. InPhenix’s 1310nm Semiconductor Optical Amplifiers (SOAs) are ideal O-Band Optical Amplifiers.

DFB Laser (Distributed Feedback Laser) - Inphenix Inc. https://www.inphenix.com/en/distributed-feedback-lasersdfbs/ Inphenix’s #DFBlaser has a simple and low-cost fabrication process and has many advantages, such as a very high side mode suppression ratio, stable operation over a broad temperature range, narrow linewidth and low sensitivity to optical feedback. #DistributedFeedbackLaser (DFB Laser) is an edge-emitting semiconductor light source. Compared to FP Lasers and DBR Lasers, DFB Lasers are much more stable and generate a clean single mode output. This is achieved by the inclusion of a diffraction grating along the active region of the chip.

Broadband Light Source - Inphenix Inc. https://www.inphenix.com/en/broadband-light-source-modules/ A broadband light source, also known as a superluminescent source is a superluminescent diode that is perfect for OEM integration. #Broadbandlightsources are utilized for ultrahigh-resolution optical coherence tomography, passive component testing, and multi-channel fiber Bragg grating interrogation. The light output may be via continuous internal-to-external fiber or by optical fiber adapter for removable pigtail interconnectivity. Central wavelength windows of operability range from 700nm to 1700nm, delivering high power densities across wide FWHM bandwidths.
