Helica™ In - Fiber Circular Polarizer Chiral Photonics, Inc. (CPI), introduces an all-glass, in-fiber polarizer based on its proprietary chiral technology that provides a circularly polarized output in a fiber format. The polarizer can be manufactured to meet your spectral and performance specifications, including central wavelength, bandwidth and extinction ratio requirements. Specifications and an exemplary spectrum are shown below. Pigtailing and connectorization of the device can be customized as needed. Harsh environment requirements can also be accommodated, including chemical, temperature and radiation resistance. Please call us to discuss your specific requirements and receive a prompt quotation. Applications: Polarization measurement and control Optical sensors Test and measurement instrumentation R & D Specifications: PROPERTIES Central Wavelength1 980 nm, 1064 nm, 1310 nm, 1550 nm Bandwidth > 50 nm Extinction Ratio2 >25 dB Typical Insertion Loss <2 dB Package Style Flexible stainless steel microtube (28 cm long) under 900 µm furcation tubing Pigtails3 PM or SM, 1 m,  inside 900 µm furcation tube Operating Temperature -50 to +50○C Storage Temperature -70C to +85C 1Other wavelengths available upon request 2This extinction ratio is guaranteed at the polarizer output but pigtail choice and handling may affect resultant output. Passing polarization can be either right- or left-handed. 3Connectorization available upon request. Typical output fiber is commercially available PM fiber that maintains circular polarization, such as manufactured by IVG Fiber.
