As illustrated in the figure to the right, the core of the Micron Optics’ high-speed swept laser incorporates a Semiconductor Optical Amplifier (SOA,) a high-performance FFP-TF, and the associated isolators and couplers to form a uni-directional ring laser. This unique design embodies the collective advantages of the SOA’s broad gain-bandwidth with direct modulation capability, and the Micron Optics FFP-TF’s wide tuning ranges (i.e., free spectral range (FSR) > 200 nm), high finesse (1000 to 10,000), low loss (80 dB.
When configured as a seed laser followed by post amplification, the swept spectrum and power can be optimized for high-sensitivity imaging, remote sensing, and nonlinear wavelength conversion applications. Furthermore, when combined with a dispersive element, the wavelength sweep can be converted into high-speed and wide-angle spatial scanning without moving parts. Depending on applications, the laser generally needs to be optimized to meet varying combinations of requirements including the sweep range, linewidth, power, speed, and center wavelength.
