Product information "Gershwin & Guaraldi EPG Polarization Entangled Photon Sources"

Polarization Entangled Photon Source; Fiber-coupled or Free Space; Type-0, Type-1, Type-2 Phase Matching

Crystal-based, OZ Optics’ Gershwin & Guaraldi EPG polarization entangled photon source product line produces polarization entangled photon pairs through the process of spontaneous parametric down conversion (SPDC). These OEM sources are compact interferometers which can be configured for type-0, type-1, or type-2 phase matching.

Variants which support type-0/type-1 are called Guaraldi, while those supporting type-2 are called Gershwin. Both Guaraldi and Gershwin come optically coupled via fiber to free space focusers with pre-selected beam waists which can be customized upon request. Guaraldi and Gershwin are OEM-style devices designed to support the quantum optics R&D community.

Using a laser, a dichroic beam splitter, tomographic measurement equipmen t (half wave plate (HWP), quarter wave plate (QWP), polarizing beam splitter (PBS)), and single photon detectors (e.g. IDQube), it takes seconds to measure photon pairs, and only a few trial settings of the HWP to generate and confirm very high quality (>95% fidelity) polarization entanglement.

Guaraldi and Gershwin can be operated in two modes:

Pair production mode: To create pairs, the HWP is set to 0 or 45 degrees. The generator is pumped with a suitable (correct wavelength) laser and the output can be split with either a 50:50 beam splitter or a dichroic.
Polarization entanglement mode: Here, the operation is identical to pair production mode except that the HWP is set to 22.5 degrees. Further optimization of the entanglement quality can be achieved by small adjustments to the HWP setting if desired.

AGI Graded Index MM Fibers

Multi Mode, Graded Index; 850, 1300 nm; Core Diameter 50, 62.5 µm; Cladding Diameter 125 µm; Coating Acrylate, Polyimide, Aluminium, Gold; Numerical Aperture 0.20, 0.275Fiberguide’s AGI series of anhydrous graded index multi mode silica core, silica clad, polymer or metal coated fibers feature a graded index profile instead of a step index profile. These fibers are primarily used in data transmission applications where more bandwidth is needed than step index fibers can offer. These fibers are available with acrylate coatings (-Y) and also high performance polyimide (-T), aluminum (-A) and gold (-G) coatings that allow them to exceed the temperature performance levels of standard fibers. As a further option, AGI series fibers can be provided with a broad selection of shaped tips – standard configurations as well as custom designed shapes. Shaped tip fibers provide optimum control over beam delivery and/or increased efficiency of light collection. AGI series fibers can also be end capped to achieve higher coupled power into a fiber core by reducing the power density at the air / silica interface, commonly the point of laser damage. End cap diameters and lengths are offered for select numerical apertures and fiber cores size, but can be easily customized for a variety of fiber types and specialized applications. Additionally, all fiber types can be equipped on demand with Fiberguide’s patented RARe Motheye anti-reflective technology that enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range.
