The FP3007x is based on a single-frequency Distributed Feedback Laser (DFB) chip. This type of device offers mode-hop free performance when temperature tuned around its room temperature wavelength. The optical output beam is diffraction limited, single lateral and longitudinal mode. Mode-hop free over temperature and time. Facets are passivated for reliable performance at high power. The DFB laser chip can be packaged in several options: TOSA, Butterfly and TO-8. These packages can have a fiber pig-tail or window optical output.
