EVANESCENT FIELD POLARIZERS 
Phoenix evanescent field fiber optic polarizers are produced by replacing the cladding in the locally processed region of the fiber with a polarization selective material. Within the polarizing region one polarization mode of the single mode fiber is highly attenuated and the other mode propagates with virtually no loss. Extinction ratios above 50dB are readily achievable whilst maintaining extremely low transmission loss of the required polarization mode. This non-invasive technology leaves the fiber core continuous providing optimum performance.		 OPERATIONAL
WAVELENGTH RANGE
Phoenix range of polarizers will polarize light of any wavelength from 1280nm to 1625nm in Corning SMF28 fiber. Typically extinction ratio and insertion loss increases with wavelength for the SM/SM devices. The polarizers are specified for a particular wavelength range although they are operational outside the band, performance may differ slightly to the specification. Polarization maintaining polarizers have a flat extinction ratio response across the band offering broadband benefits in certain applications.

Notes to Specifications
_• All specifications are worst case for the
_• wavelength range selected; actual products
_• commonly exhibit better performance.
_• All polarizers are tested and graded into
_• performance groups.
_• SM – single mode fiber: PM – polarization
_• maintaining fiber.

1. The devices will provide polarization over the full wavelength range for which the fiber is single mode. Performance characteristics are wavelength dependent and the devices will meet specification as follows:
_•  Type 15 – 1530nm to 1625nm
_•  Type 14 – 1480nm to 1530nm
_•  Type 13 – 1280nm to 1320nm
2. These are the maximum extinction ratios typically achievable for each of the options. If alternative values are required please discuss with our sales representative.
3. Insertion loss is typically in the region of 0.2dB (SM/SM) to 1dB (PM/PM), excluding connectors.
4. The all-fiber technology gives an excellent return loss figure of >70dB.
5. Dimensions are in mm. Standard – POL, miniature –MPOL.
6. The operating temperature range is specified for typical telecommunications operation. Please discuss with the sales representative if operation outside the specified range is required.
7. The devices are very robust for storage and transportation.
8. Standard single mode Corning SMF 28 fiber is used for the SM devices and PANDA polarization maintaining fiber for the PM devices. The technology is applicable to any fiber type; please contact the sales representative to discuss any alternative fiber.
9. Pigtails are typically no shorter than 1m.

EVANESCENT FIELD POLARIZERS 
Phoenix evanescent field polarizers are produced by replacing the cladding in the locally processed region of the fiber with a polarization selective material. Within the polarizing region one polarization mode of the single mode fiber is highly attenuated and the other mode propagates with virtually no loss. Extinction ratios above 50dB are readily achievable whilst maintaining extremely low transmission loss of the required polarization mode.		 HIGH GRADE RANGE
Phoenix has an extensive selection of polarizers to meet different applications and budgets. The high-grade range shows the full capability of the evanescent field technology providing very high extinction ratio with low excess loss of the required polarization state over a wide band of wavelengths. These are designed specifically for applications in which very pure polarization states are required.
