PSW-002 Polarization Switch

Product information "PSW-002 Polarization Switch"

1310, 1550 nm; IL <0.5 dB; Switching Speed 100 µs; Polarization Rotation 45°, 90°; ER >18 dB; RL >55 dB

General Photonics’ PSW-002 is a solid-state polarization switch that can quickly and repeatably rotate the state of polarization (SOP) of incoming light by a fixed angle, either 45° or 90°. Both single mode (SM) and polarization maintaining (PM) fiber pigtailed versions are available.

With the PM option, the PSW-002 device functions as a TE to TM converter, switching the SOP between being aligned with the slow and fast axes of the PM fiber, or between the slow axis and 45° from the slow axis. With the SM option, the device simply rotates the polarization ellipse either 45° or 90°.

The device can be used for polarization sensitive OCT, polarization sensitive OTDR or OFDR, PMD monitoring, polarization modulation, polarization detection, and polarization metrology. An optional driver board simplifies switch control by allowing the user to control the output SOP using TTL levels.

Accessories and Fixturing for Terahertz Gauging & Imaging
Spectroscopy Rail; Collinear Adapter; Lens Options, T-Image Platform Luna’s T-Ray ASR5001 is the first compact pulsed terahertz measurement system that is robust enough to be deployed in an industrial environment and has all of the flexibility provided by Luna’s fiber-coupled sensor heads in a rack mount package. With Luna’s range of accessories and fixturing devices, the T-Ray® 5000 can be configured to fit your specific application. With its exceptionally long high-speed delay, the T-Ray® 5000 is ideally suited for spectroscopic investigations, providing spectral resolution down to 1.5 GHz at 100 Hz. The transmitter (HTS40nm) and receiver (HRS40n1) can be mounted on the T-Ray® ASR5001 spectroscopy rail to perform transmission spectroscopy measurements. A standard mount is provided to hold accessories or standard sample cards. The rail can accommodate lenses up to 150 mm working distance. An iris is provided on the sample holder to block any portions of the beam that may not be going through the sample. Tip-tilt stages provide easy optimization of the beam alignment to ensure maximum bandwidth. Using the T-Ray® 5000 AXA40n1 collinear adapter, transmitter and receiver can be coupled to perform as an integrated collinear reflection transceiver. Alignment pins provide precise positioning. The adapter has two ports for the lens, so it can be assembled as right or left-handed. Reflection measurements are easily acquired because the transmitter and receiver share the same lens. Spatial resolution down to 100 µm has been obtained using this arrangement with a 25.4 mm focal length lens. The transceiver is ideal for reflection tomography. When used with an HTS40nm and an HRS40n1, the assembled collinear transceiver based on ASR5001 or AXA40n1 will provide over 3.5 THz of bandwidth and SNR of 70 dB (ASR5001) or 60 dB (AXA40n1) respectively. The T-Ray® 5000 HTS/HRS Transmitters & Receivers come standard with a 38 mm diameter lens in an adjustable lens tube. In addition to that, Luna offers T-Ray® 5000 lens options ranging from 38.1 mm to 76.2 mm and 152.4 mm in diameter, with focal lengths ranging from 25.4 mm and 76.2 mm to 152.4 mm and 304.8 mm, plus a collimating lens. Here, the “focal length” is the distance from the lens surface to the beam waist. Lens tubes that mount on the transmitter or receiver are also available for 38.1 mm and 76.2 mm lenses. The lenses are manufactured from high-density polyethylene (HDPE) and are manufactured to an aspheric profile for high-quality focusing across a wide range of frequencies. Luna has specifically designed these lenses for use with their fiber-coupled transmitter and receiver sensor heads. When mounted on the front of a transmitter, the lens will provide a collimated or a focused beam. Use relay lenses in conjunction with a collimating lens on the sensor head. The collinear adapter (AXA5001) and the integrated collinear transceiver (HXC50xn) are compatible with 38.1 mm diameter lenses. The T-Ray® 5000 MSL5201 T-Image platform can be positioned for horizontal or vertical scanning. The transmitter and receiver can be configured in transmission or collinear reflection geometry by using the collinear adapter. The MSL5201 can move at speeds up to 150 mm/s and can provide step resolutions below 30 µm. The motors are integrated with the required amplifier and encoder to allow high-quality images to be acquired at speeds up to 1000 pixels/s. The T-Ray® 5000 MSL5201 T-Image platform has an embedded motion controller that is configured by software running on the Terahertz Control Unit.
