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 are shown below. The circular polarizer acts as a quarter waveplate and the quality of the output circularly polarized light is dependent on the quality of the linearly polarized light that is input into the device. Pigtailing and connectorization of the device can be customized, as needed. However, an output connector is not recommended. The output SM fiber should be kept as short and unperturbed, mechanically and thermally, as possible. Chiral Photonics has not tested an output fiber that has demonstrated maintenance of good circular polarization extinction ratio (cPER), similar to what exists for linearly polarized light. 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 PROPERTIES Central Wavelength 1: 980 nm, 1064 nm, 1310 nm, 1550 nm Bandwidth: >50 nm Extinction Ratio 2: >25 dB Typical Insertion Loss: <2 dB Package Style: Rigid or Flexible, see schematics below Pigtails 3: PM input, SM output, 1 m Operating Temperature: -50 to +50 C Storage Temperature: -70 to +85C - Other wavelengths available upon request - This extinction ratio is guaranteed at the polarizer output but pigtail choice and handling may affect resultant output. Circular polarization can be either right- or left-handed. Typically the slow axis is converted to right-handed, circularly polarized light. - Connectorization available upon request.
The PSC611 is an all-glass, pump-signal combiner that offers: - Information loss of 0.5 dB or less on all channels - Polarization extinction ratio (PER) greater than 23 dB maintained through the signal channel - Flexible and scalable design, based on Chiral Photonics' proprietary pitch reducing optical fiber array (PROFA) technology, with independent control of channel spacing, mode field diameter, and channel count. Speak to us about your custom or OEM needs as this design facilitates use at 1060 nm as well as the shown 1550 nm configuration. The design can also be modified to suit your specific fiber needs: PARAMETER UNIT SPECIFICATION Signal Channel - Input Input Fiber Insertion Loss Return Loss PER 2 s dB dB dB SMF28 or PANDA 1550 1 <= 0.4 40 23 Pump Channels Number of Channels 1 Pump Fiber 1 Operating Wavelength Insertion Loss s s nm dB 6 105/125 pm core / cladding, NA: 0.12 800-1600 < 0.3 Dual Clad Fiber Output Fiber 1 Operating Wavelength 1 s nm 6/125/245 µm core / clad / clad2, Er:Yb-doped, NA: 0.18 / 0.46 1530-1625 Mechanical Specification Package Type 3 N C P None Connectorized Packaged (typical: 150 x 6 x 6 mm) - Speak to us about other wavelength requirements as this design can accommodate both Er (1550 nm) and Yb (1060 nm) bands.
