摘要： Controller calibration methods for use with sampled grating distributed Bragg reflector SGDBR laser (102) is presented. An exemplary method includes conducting a two-dimensional mirror current scam of each front mirror current setting and back mirror current setting for a sampled grating distributed Bragg reflector SGBDR laser(102) to produce laser setting data corresponding to each front mirror current setting and back mirror current setting to generate a reference optical signal (114) of the SGDBR laser (102). A channel operating point is determined for each channel within the two-dimensional scan data. A fix up of the operating point to substantially minimize wavelength and power error can also be performed. A two-dimensional control surface is characterized at the channel operating point for each channel. A lookup table for controlling the SGDBR (102) laser is generated from the operating point currents, locker values and two-dimensional control surface data from each channel.

摘要： A laser tissue fusion device is optimized for particular surgical applications to join tissue layers. The device has two opposed arms that engage and disengage to clamp and release layers of tissue therebetween. The distal end of the first arm is disposed opposite the distal end of the second arm. A laser energy source generates therapeutic laser energy is either integrated within the device is a separate unit. An energy pathway transmits the laser energy to the distal end of the first arm to deliver the laser energy to tissue layers clamped between the distal ends of the arms. An actuator decreases the separation distance between the distal ends of the arms to clamp the tissue layers and activates the laser energy source upon engagement. The laser energy source delivers a burst of energy at a predetermined wavelength for a predetermined period of time sufficient to spot weld the tissue.

摘要： A compact multiwavelength transmitter module for multimode fiber optic ribbon cable, which couples light from an M×N array of emitters onto N fibers, where the M wavelength may be distributed across two or more vertical-cavity surface-emitting laser (VCSEL) chips, and combining emitters and multiplexer into a compact package that is compatible with placement on a printed circuit board. A key feature is bringing together two emitter arrays fabricated on different substrates—each array designed for a different wavelength—into close physical proximity. Another key feature is to compactly and efficiently combine the light from two or more clusters of optical emitters, each in a different wavelength band, into a fiber ribbon.

In one embodiment, the blood purifier device includes a pair of end plates and a first cylindrical tube located between the end plates. The blood purifier device also includes a porous tube contained within the space defined by the first cylindrical tube. An inlet provides unpurified red blood cells into blood purifier device. An electrode generates a negative potential across the porous tube to repel red blood cells so that the waste particles pass through the porous tube and the red blood cells do not. An outlet can be coupled to one of the end plates to receive the purified red blood cells.

摘要： A spatially modulated waveguide Bragg grating mirror is suspended over a substrate by plurality of fingers extending laterally away from the waveguide centerline. The positions of the fingers are coordinated with the positions of crests and valleys of amplitude or phase modulation of the Bragg grating, to avoid disturbing the Bragg grating when it is tuned by heating. When the Bragg grating is heated, the heat flows through the fingers creating a quasi-periodic refractive index variation along the Bragg grating due to quasi-periodic temperature variation created by the heat flow from the grating through the supporting fingers. Due to coordination of the positions of supporting fingers with positions of the crests and valleys of modulation, the optical phase coherence is maintained along the Bragg grating, so that the spectral lineshape or filtering property of the Bragg grating is substantially preserved.

摘要： A bias-control circuit that provides operating point control for a Mach-Zehnder modulator experiencing optical absorption at their interferometric arms. The bias control circuit generates compensation signals that are used to counter the thermally induced index shifts as a result of absorption. In addition, an operating point with desirable transmitter characteristics can also be arbitrarily chosen by over-compensating or under-compensating thermal effects.

摘要： A septal stapling apparatus includes an instrument body having proximal and distal end portions. A handle at the distal end portion enables a user to hold and manipulate the instrument body. A pair of spaced apart arms are extending from the handle and include a staple arm and a tensioning arm. The body provides a trigger that moves between resting and firing positions. An actuator link moves between first and second positions, the actuator link being moved by the trigger, wherein the actuator link includes a staple moving member that is attached to the staple arm. The staple arm has a staple bank that includes multiple staples. The trigger, actuator link, staple bank, and staple moving member are configured to move a staple to a stapling position when the trigger is pulled. The staple arm and tensioning arm move together when the trigger is pulled.
