ABSTRACT:
A device (10) for processing an optical signal (28) is provided. The device includes a refractor (12) having first (34) and second (36) ends and having a reflecting surface (16) for reflecting the optical signal (28) by total internal reflection. The device also includes a switchplate (20) having first (44) and second (46) ends, a contact surface (22) for contacting the refractor (12), and wherein one end (44 or 46) of the switchplate (20) is secured to the refractor (12). An actuator (40) provides a force that moves the switchplate (20) with respect to the refractor (12). The switchplate's contact surface (22) can frustrate the total internal reflection of the optical signal (28) by the refractor's reflecting surface (16) when the contact surface (22) of the switchplate (20) is in proximal contact with the refractor (12).
