Patent number: 6278549Abstract: An optical filter including a plurality of dielectric layers is provided on a quartz substrate. Quartz is advantageous as a substrate material because it has relatively low loss at wavelengths commonly used in telecommunication systems. Moreover, it is thermally and chemically stable, and has good adhesion to most dielectric films used as quarter and half wave layers. Further, quartz is mechanically tough, relatively inexpensive and readily available. The quartz substrate is cut from a crystal and has an orientation with reduced birefringence. In addition, the thickness of the quartz substrate is selected to reduce temperature-related shifts in the center wavelength of the filter.Type: GrantFiled: April 17, 2000Date of Patent: August 21, 2001Assignee: CIENA CorporationInventor: Carl E.

Patent number: 5737349Abstract: An optical isolator comprises an input polarizer configured to pass light at a predetermined optical polarization axis to a Faraday rotator and thereafter through an output polarizer. A magnet is disposed remotely and laterally away from the Faraday rotator, such that the external field of the magnet maintains the magnetization of the Faraday rotator substantially saturated. In accordance with another aspect of the invention the output polarizer is rotatably adjustable to substantially fine tune the isolator to a given laser wavelength. To this end light is transmitted through an input polarizer, and through a Faraday rotator magnetized in a first magnetization direction so as to rotate the polarization axis of the light passing through the Faraday rotator. The output polarizer is rotatably adjusted until such time that substantially no light travels through the output polarizer.Type: GrantFiled: May 22, 1996Date of Patent: April 7, 1998Assignee: Lucent Technologies Inc.Inventor: Carl E.

Patent number: 5684901Abstract: An apparatus minimizes the spherical aberration of a light beam emitted into an optical fiber from a light source such as a laser beam. The laser emits a light beam along a path of travel to an optical fiber used in a telecommunication system. A ball lens is positioned within the light beam path of travel, and has a front focal point. The laser is positioned in front of the front focal point such that the light beam emitted by the laser forms an intermediate paraxial focus point. A corrective lens is positioned adjacent the paraxial focus point so that the laser beam is introduced into an optical fiber with minimal spherical aberration and increased coupling efficiency. The corrective lens is displaced radially off-center to compensate for misalignment aberrations and coma.Type: GrantFiled: February 14, 1996Date of Patent: November 4, 1997Assignee: Lucent Technologies Inc.Inventor: Carl E.

Patent number: 5264392Abstract: A novel optical subassembly arrangement is proposed. The subassembly comprises a silicon-based submount including a plurality of openings for placement of the various optical components utilized to form the optical subassembly. In particular, a silicon wafer is processed (e.g., etched) using conventional techniques to simultaneously form a large number of individual submounts, each submount processed to include a number of openings. The silicon processing may be sufficiently controlled such that active alignment of the components is minimized. An important feature of the design, when associated with an isolated embodiment, is that the silicon submount is formed to include openings for both the laser and isolator optics such that the openings are disposed along a thermal transport path through the silicon substrate from an attached thermoelectric cooler (TEC). Therefore, the laser and isolator optics are maintained at the same operating temperature.Type: GrantFiled: October 1, 1991Date of Patent: November 23, 1993Assignee: AT&T Bell LaboratoriesInventors: Carl E. Gaebe, Xian-Li Yeh

Patent number: 4981335Abstract: An optical package arrangement is disclosed which is capable of reducing internal reflections while maintaining a common axis between the input device (for example, a laser diode) the output device (for example, an optical fiber) and various elements interposed therebetween. The output device is designed to include a bevel angle (.beta.) for redirecting reflections away from the common axis. In accordance with the teachings of the invention, an optical element (for example, an isolator, filter, window or any combination thereof) is inserted between the input and output devices and oriented at a tilt angle (.theta.) so that reflected signals from the element are also redirected away from the common axis. Focusing means disposed between the optical element and the output device is appropriately sized (in terms of focal length) so as to ensure maximum coupling of the signal into the output device along a beam entrance angle (.alpha.).Type: GrantFiled: October 17, 1989Date of Patent: January 1, 1991Assignee: AT&T Bell LaboratoriesInventor: Carl E.
