Abstract: A method and apparatus is provided for controlling the optical output power from an optical amplifier arrangement. The arrangement includes a rare-earth doped fiber for imparting gain to an optical input signal propagating therethrough, a pump source for supplying pump power to the rare-earth doped fiber, and a tap for receiving a portion of the output power generated by the rare-earth doped fiber and converting it to a control signal. A controller is also provided for receiving the control signal and generating a bias current in response thereto for driving the pump source. The method begins by receiving an optical input signal that is being amplitude modulated at a prescribed frequency. The slew rate of the controller is adjusted so that the bias current drives the pump source to generate pump power that cannot vary at a rate greater than a slew-rate limit established by the controller. In this way resonance between the input signal and the frequency of the feedback control loop can be avoided.

Abstract: Two electronic devices automatically perform a synchronization session when one of the electronic devices is brought in proximity to the other electronic device. The synchronization session is initiated without user intervention based simply on the fact that the two devices have recently been brought within a predetermined distance of each other.

The two devices may determine that they are within a predetermined distance of each other using global positioning technology, via which one of the devices determines its own position and compares it to a known position of the other electronic device. Alternatively, one of the electronic devices may output a low level signal that can be received by the other electronic device when within a certain range.

Abstract: A method is provided for using an uncooled laser package having pre-established performance specifications that include a pre-established optical power level. The package is to be used at a second set of performance specifications that include a second optical power level greater than the preestablished optical power level. The method begins by applying a bias level to a laser diode in the uncooled laser package that optimizes distortion and causes the laser package to generate the second optical power level. The bias level is greater than a pre-established bias level specified to generate the pre-established optical power level. Next, the uncooled laser package is heated or cooled to maintain a substantially constant laser diode temperature.

Abstract: A surface geometry for a MOS-gated device is provided that allows device size to be varied in both the x-axis and the y-axis by predetermined increments. The actual device size is set or “programmed” by the metal and pad masks or the contact metal and pad masks. This approach saves both time and expense, since only new contact, metal and pad masks, or new metal and pad mask are required for each new device. Wafers may also be manufactured and stored at an inventory location prior to contact or metal mask, significantly reducing the time required to manufacture new devices. It is also be possible to qualify a family of devices made using this approach without qualifying each device. In addition, the location of the source or the source and gate bonding pads may be easily moved for assembly in a new package or for a new application.
