Request InfoOZ Optics LimitedOz Optics Ltd. offers miniature fiber optic polarizers of less than 4 mm in diameter that transmit rays in only one polarization, blocking light in unwanted polarization states. They feature extinction ratios as high as 30 dB, insertion losses as low as 0.6 dB and return losses of -60 dB. The polarizers operate over the entire C-, L- and S-bands, and also are available for other wavelengths. The input and output fibers can be single-mode or polarization-maintaining fibers and can be custom-terminated.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 3/29/2024Pump Laser ModulesThe uncooled pump laser modules from Coherent are made with Coherent’s G10 series laser diode technology and are meant to be used in submarine and both single- and dual-chip terrestrial...Photonics Spectra March 2024 IssueDigital Signal ProcessorThe Dove 850 from Credo is a 800G digital signal processor (DSP) integrated circuit (IC) that is optimized for linear receive optics (LRO).
