An optical system and associated method are provided. Included is a first branch capable of allowing light to pass therethrough in a forward direction and a reverse direction. The first branch includes a first medium with a first refractive index (n), and a first end and a second end. Also included is a second branch capable of allowing light to pass therethrough in the forward direction. The second branch includes a second medium with a second refractive index (n, with n&#x3c;n), and a first end and a second end. The second end of the second branch is further coupled to the first branch to form an angle (&#x3b8;). In use, &#x3b8;&#x2266;sin(n/n) in order to prevent the light passing through the first branch in the reverse direction from passing into the second branch, where &#x3b8;is the incident angle of the light passing in the reverse direction from the first branch to the second branch.
