The SMSR was >45 dB at a laser current of 60 mA. A static extinction ratio greater than 20 dB at a biased voltage of −3 V was applied to the EAM. Figure 22. (a) Geometry of the SiNx mask and (b) schematic diagram of an EAM integrated with a tunable DBR laser. Reprinted ...
Semiconductor optical amplifiers (SOA) are essentially a laser diode with no feedback from its input & output ports and hence is also referred to as a Traveling-Wave Amplifier. InPhenix’s 1310nm Semiconductor Optical Amplifier is ideal O-Band Optical Am
A semiconductor laser device includes a semiconductor laser element having an active layer and semiconductor layers on opposite sides of the active layer, and a PN-junction diode in part of the semico
We experimentally and theoretically investigate the pulsed emission dynamics of a three section tapered semiconductor quantum dot laser. The laser output is characterized in terms of peak power, pulse width, timing jitter and amplitude stability and a ra
The unique property of BLEs is the combination of the high brightness of a laser diode with a broad optical spectrum and hence the low coherence of a light-emitting diode. BLEs have emerged as the ideal core optical sources for numerous industrial and medical applications, such as fiber-optic...
