摘要： According to embodiments of the present invention, an optical modulator control apparatus receives a data signal and determines amplitude and cross-point of the data signal using a full wave detector. The apparatus sums the negative and positive halves of the data signal to determine the amplitude and differences the negative and positive halves of the data signal to determine the cross-point. Measurement of the amplitude may be independent of the cross-point.

摘要： An apparatus for optical receiver circuit protection includes a bias source, a bias monitor, and a comparator. The bias source is to provide a bias voltage to an optical receiver. The bias monitor is coupled to measure a current through the optical receiver, where the current changes responsive to received optical energy. A comparator is coupled to the bias monitor, where the comparator has a first state if the current is less than a threshold current level and where the comparator has a second state if the current is greater than the threshold current level. The bias source is coupled to be enabled responsive to the comparator switching to the first state and disabled responsive to the comparator switching to the second state.

摘要： Described herein is a hermetic fiber optic package that may have a wide bandwidth radio frequency (e.g., between 9 kHz and 300 GHz) interface and a multilayer substrate provides a platform to integrated various components such as, for example, integrated circuits having electronic components, optoelectronic components, or optics. In one embodiment, the substrate has a wide bandwidth surface mountable interface that may be a single ended or a differential that allows for an electrical signal to pass from the exterior of the package to the interior. The interior of the package contains a “riser” that is used to bring an electrical signal from the plane of the substrate to the plane close to the optical axis. This riser includes a transmission line to achieve the change in height. The transmission line can be single ended or differential. Also within the package is a “submount” upon which electrical/optical/electro-optic components can be integrated.
