The device is a compound Si-PIN structure. To reach high response, back side hole etching process is used for thinner I layer, when carrier go through the floating area, optical current will appear .Slow optical carrieIP are shorted for fast response purpose.We has our Patented package Desgin-“Bullet” design adopts Two optimized chips special for different wavelength.
One we called Circle Chip and the other is square Chip.
Circle chip has the peak response wavelength near 950nm.It has good response to the wavelength near 1060nm.
Square Chip has the peak response wavelength near 900nm.It has good response to the wavelength @450nm~650nm Devices can be pigtailed with any size optical fiber that is compatible with its active area size. Pigtails range in core size from 3um to 100 micron. One meter is the standard length, but any length or connector termination may be specified. Pigtails may be terminated with ST, FC, SC and LC connectors with either PC or APC polish.
