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.

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.
