An alternative type of 3-port polarization-independent optical quasi-circulator by utilizing a pair of holographic spatial walk-off polarizers (HSWPs) is proposed. This device consists of a reflection prism, three polarization beamsplitters cubes, a pair of HSWPs, a Faraday rotator, and a half-wave plate. The operating principles, the characteristics and the performances of this device and HSWPs are discussed. In order to show the validity, the prototype device operating in 1300nm is assembled and tested experimentally. The merits of this design include polarization-independence, compactness, high isolation, and easy fabrication. It should also be possible to design the device operating at 1550 nm wavelength range.
