Abstract
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<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 (θ). In use, θ≦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 θis the incident angle of the light passing in the reverse direction from the first branch to the second branch.
