Broadband Polarizing Beam Splitter

Our broadband non polarizing hybrid cube beamsplitters are ideal for use with multiple lasers or tunable sources.

Broadband polarizing beam splitter.

Even power split ratio insensitive to polarization. Broadband polarizing plate beamsplitters consist of a thin layer of aluminum microwires adhered to a glass window. These beamsplitters are an alternative and economical substitute for ruled or holographic wire grid polarizers. Incoming beams are both transmitted and reflected 45 with the s and p polarized components matched to within 10.

An ultra broadband polarization beam splitter pbs with low excess loss el and a high extinction ratio er is proposed and demonstrated for the case with 340 nm thick silicon on insulator waveguides.

Here the pbs is realized by using cascaded adiabatic dual core tapers which consist of a strip core and a subwavelength grating core. P polarized light is transmitted while s polarized light is reflected both with negligible absorption. 10 5 laser quality r unp. The asymmetric directional coupler consists of a regular strip waveguide and a sub wavelength grating swg waveguide.

We design and experimentally demonstrate a polarizing beam splitter pbs on a silicon on insulator soi platform based on an asymmetric directional coupler. The polarizing beam splitter coatings generally perform poorly outside the designed spectral range so the pbs124 will not be suitable around 1800nm. A polarizing beamsplitter cube splits randomly polarized beams into two orthogonal linearly polarized components. An unpolarized beam is split into two orthogonal linearly polarized components.

Designed for broadband applications techspec broadband polarizing cube beamsplitters offer a transmission of greater than 90 for p polarized light and a reflection efficiency of greater than 99 for s polarized light across the entire design wavelength range. 1 0 in to 4 0 in diameter tolerance. Providing exceptional image contrast and uniformity these beamsplitters are ideal for applications requiring large angular apertures and high throughput. A dielectric coating provides long term stability.
