The WHS302 heatsink can be used to support following laser diode drivers and temperature controllers from Wavelength Electronics: WTCP5V5A, WTC3243, WTC3243HB, WHY5640, LDTC 2/2 O, LDTC 2/2 E, WLD3343, WLD3343-2L, WLD3343-3A, WLD33ND-3L or WLD3343HB. The controllers operate to 500 mA without any additional heatsinking (assuming 5 V operation). To operate up to 1 A, add the thermal washer WTW002, and WHS302 heatsink. To operate to the full 2.2 A, add a fan WXC303 (5 V) or WXC304 (12 V). For convenience, a kit with two 0.75" and two 1" screws is available: WXC305. Kits combine these elements: WEV300 (includes thermal washer, heatsink and screw kit), WEV301 (includes thermal washer, heatsink, screw kit, and a +5 V fan) or WEV302 (includes thermal washer, heatsink, screw kit, and a +12 V fan).Key Features Convenient and simple design  

 1280-1620 nm; SOP Uncertainty ±0.25°; DOP Uncertainty ±2%, ±0.5%; PER Measurement Range 0-40 dB; Polarization Sampling Rate 4 MHz; Analog Bandwidth ≤1 MHz General Photonics’ POD-201 is an FPGA-powered polarimeter designed for high-speed polarization analysis and monitoring. The instrument uses four channels to simultaneously obtain the four Stokes parameters and measure the instantaneous state of polarization (SOP) and degree of polarization (DOP) of an input light beam. The POD-201 polarimeter is controlled with FPGAs that support sampling rates of up to 4 MS/s. A USB 2.0 interface enables data to be transferred directly to a computer at a rate up to 30 MB/s. The POD-201 also features data logging function for long term measurement of polarization changes of up to 1 billion points. In addition to the front panel controls, the unit can be controlled remotely via the USB 2.0 interface. The POD-201 comes with PolaView™ software for real-time graphic display of polarization state either on a Poincaré Sphere window for viewing SOP traces or on an oscilloscope window for monitoring polarization changes over time. The POD-201 polarimeter can be quickly and easily calibrated using its built-in self-calibration program to optimize DOP and SOP accuracies at special wavelengths and temperatures. With a suitable light source and measurement techniques, it can be used to measure polarization extinction ratio (PER) to aid in aligning PM fiber to laser sources. Further features include long-term SOP monitoring, SOP markers for angle measurement, a "SOP replay" function in sphere display mode, extended triggering capability in oscilloscope mode, an OLED display for easy setup and data display and a configurable analog SOP/DOP/power output for easy integration with automated test systems. The standard configuration is a two-port inline version, to monitor a signal without interruption.

Polarization Sensitive & Insensitive Versions; SM or PM Fiber; 532 nm to 2000 nm; Isolation ≥20 to ≥40 dB; Power Handling 0.5 to 10 W This complete line of pigtailed fiber-to-fiber isolators for wavelengths ranging from 532 nm to 2000 nm combines a free-space Faraday rotator with polarizing optics to provide up to 60 dB of isolation and high power handling with minimum losses. Our isolators are manufactured using OZ Optics' patented tilt alignment technique. Input light from an optical fiber is first collimated, then transmitted through the isolator optics. A focusing lens on the output side of the isolator then couples the light back into the output fiber. This method is highly flexible and allows isolators capable of handling up to 10 W of optical power through single-mode fibers. Isolators are offered in two different versions, polarization sensitive and polarization insensitive. Polarization sensitive isolators are well suited for PM fibers and for some applications where an input free-space beam of constant polarization enters the Faraday optics. However, these isolators are not recommended for SM fibers, as these fibers do not maintain polarization. For this reason we recommend using polarization insensitive isolators with standard SM fibers. Please note however that polarization insensitive isolators are not necessarily available for all wavelengths or power levels.

1060, 1310, 1550 nm; IL <1.2, <0.1 dB; SOP Recovery Time 0.9 ms; Tracking Speed 47 π/s; SOP Accuracy <0.1 dB; RL >50 dB General Photonics’ POS-002 polarization tracker automatically adjusts the state of polarization (SOP) towards a reference SOP, counteracting continuous input SOP variations as fast as 0.9 ms with no resets. The reference SOP is determined by a feedback signal which can be provided either internally or externally. The internal feedback version (POS-002-I) consists of a fiber squeezer polarization controller, in-line polarization monitor, digital and analog circuits, and proprietary algorithm. The error signal from the polarization monitor is fed back to the polarization controller to maintain a linear SOP at the output. The output fiber for POS-002-I is typically polarization maintaining (PM) fiber with the SOP aligned to its slow axis. The external feedback version (POS-002-E) replaces the internal polarization monitor with an external analog electrical feedback signal of the user’s choice, such as a voltage proportional to the degree of polarization (DOP) measured by a polarimeter, the bit-error rate (BER) from a BER chip, the RF spectrum of a detected signal, or the optical power after a polarizer. The output fiber is typically single mode (SM) fiber.
