| 193 | Fourier-plane photonics package | US712530 | 1996-09-11 | US5857048A | 1999-01-05 | Mark D. Feuer; Joseph E. Ford |
| A photonics package, and methods for its use are disclosed. In one configuration, a collimating lens is disposed between a photonics device and a ferrule containing two optical fibers. Preferably, one of the fibers delivers an optical signal to the photonics device, and the other fiber receives an optical signal from the photonics device. The fibers within the dual-fiber ferrule are located off of the optical axis of the lens so that light emanating from the signal-delivering fiber will be imaged onto the photonics device at a slight angle from the normal and may be reflected at the same angle for coupling into the signal-receiving fiber. Preferably, the photonics device is situated at the Fourier plane to facilitate coupling reflected light into the signal-receiving fiber. The function of the photonics package varies with the included photonics device. For example, the package can function as a data receiver, a data transmitter and a data transceiver by incorporating, respectively, a photodetector, an optical modulator, and a transceiver. The photonics package, which can be integrated in optical communications networks, allows for incoming and outgoing signals to be handled on separate fibers, obviating the need for a splitter as required in one fiber systems. A decrease in signal loss throughout the optical communications system can thus be realized. | ||||||

| Methods and apparatus are disclosed for the correction of presbyopia by reprofiling the cornea to create at least one region having a different focal point, and thereby assist the eye in accommodating for close-viewing conditions. According to the invention, at least one region of different curvature is created by photoablation of the cornea to permit the eye to accommodate for near objects. This "add" region is preferably located near the center of the optical zone and preferably within Bowman's membrane or the adjacent upper portions of the stroma, which lies directly below Bowman's membrane. Apparatus is disclosed, including a laser means and a beam-shaping means, disposed between the laser means and the surface of the cornea, which imposes a defined ablation profile upon the cornea. The system can also include a feedback control means for measuring the effectiveness of the laser during operation and for controlling the laser. The beam-shaping means can include either an aperture e.g., a beam-shaping stop means alone or in combination with a beam-shaping window, or a mask which is photodecomposable or otherwise graded in its absorptive capacity to present a predefined profile of resistance to the laser radiation. | ||||||
