摘要: A laser biasing stabilization circuit and method uses the second derivative of the optical light output of a laser with respect to the current through the laser, d.sup.2 L/dI.sup.2, in a feedback loop to control the laser bias current through the laser. The modulation current in the laser is controlled using a second, average power feedback loop.

摘要: A multilayer ceramic package for optical devices is disclosed for use in both high and low bit rate applications. A side portion of the multilayer package is formed to provide a multilayer microwave input connection for a high bit rate signal. In an exemplary arrangement, an intermediate ceramic layer of the multilayer structure is defined with an appropriate thickness and metallized on areas of the top and bottom surfaces. This combination thus forms a multilayer microwave connection defined as a microstrip. Other multilayer configurations, for example, a stripline, may also be used. By utilizing a multilayer microwave connection in place of a conventional electrical connection, the impedance of the high frequency input source can be better matched to the optical device.
