Patent ID: 6947628

Claim:
An optical add-drop switch, comprising: a first switch, comprising: a first wavelength dispersive medium, a first lens optically coupled to the first wavelength dispersive medium, a first segmented beam steering device optically coupled to the first lens at a side opposite to the first wavelength dispersive medium, wherein each segment is independently configured, and a first mirror optically coupled to the first lens at a side opposite to the first segmented beam steering device; and a second switch comprising: a second wavelength dispersive medium, a second lens optically coupled to the second wavelength dispersive medium, a second segmented beam steering device optically coupled to the second lens at a side opposite to the second wavelength dispersive medium, wherein each segment is independently configured, and a second mirror optically coupled to the first mirror and optically coupled to the second lens at a side opposite to the second segmented beam steering device.
