Optics for Research

An optical fiber and lens assembly which comprises a housing, an optical fiber, means for rendering the optical fiber immobile within the housing, a lens, and means for moving the lens within the housing. Such an optical fiber and lens assembly enables one to provide controlled movement of the lens, independently of the optical fiber, in response to changes in the focal length of the lens, the wavelength of light, and intended usages of the light.

An optical circulator which includes a first birefringent plate for receiving an incident beam of light from a first port, a Faraday rotator, a polarization transforming device, and a second birefringent plate immediately adjacent a second port and the polarization transforming device. The optical circulator further includes means for diverting light traveling from the second port to a direction of travel which is at a right angle to the prior direction of travel, whereby the light is directed to a third port. The diverting means is immediately adjacent the first birefringent plate and the first port, and permits the clear passage of light from the first port to the first birefringent plate. The optical circulator has a simplified design while providing for the efficient transmission of polarized light.
