Act as the light source, SLD is one of the key devices of high performance
IFOG. The design and fabricating process of SLD is optimized for IFOG.
Low PER SLD is fabricated with high stability of output optical power, high symmetry in the optical spectrum, and high reliability during all working temperature range.
Standard 8-pin butterfly structure is used for compacted hermetic package. The chip temperature can be controlled by external PCB to realize long term stable operation.
Cooperating with PANWOO PMFS, MIOC, and PINFET, the IFOG performance can be increased, such as Bias Instability and Repeatability, Angular Random Walk, and Scale Factor Linearity.
