dk photonics uses unique fusing technique and polarization maintaining fiber to build the1x2(2x2) 80um fused pm fiber coupler. the coupling ratio could be selected according to customer’s request. it features low excess loss, small size and high polarization extinction ratio. pmc is widely used for optical sensors and optical gyro.
if you do not see a standard pm fused coupler that meets your needs, we welcome the opportunity to review your desired specification and quote a custom pm fused coupler. requests for custom fiber pigtails, different wavelengths, tap ratio and handling power of operation or other specific needs will be readily addressed.
