摘要： An optical crossbar switch is described that minimizes the number of electrical components and optimizes the conversion between optical and electrical signals. Utilizing various characteristics of lasing semiconductor optical amplifiers, the optical crossbar switch provides optical components in place of traditionally used electrical components. For example, an optical buffer is described that delays an optical signal a sufficient amount of time for a path to be created for the optical signal through the optical crossbar. Additionally, a monitor/detector circuit utilizes a ballast laser signal emitted from a lasing SOA during amplification of an optical signal in order to convert optical routing information to an electrical equivalent. As a result of the multiple uses of lasing semiconductor optical amplifiers, the bandwidth of the described optical crossbar switch is greater than traditional optical crossbar switches currently in use.

摘要： An optical transistor is disclosed that provides a fast switching time, an amplified gain, and isolation. The optical transistor receives a small optical input signal at an optical base port, generates an amplified replica at an optical emitter port, and generates an inverted replica on a vertical light at an collector port. One embodiment of the optical transistor is implemented with a vertical lasing semiconductor optical amplifiers (VLSOA), wherein the ballast light is used a signal for the collector port.

摘要： An optical signal power monitoring and control system is described. The system comprises at least one lasing SOA that receives, amplifies, and outputs the optical signal. During the signal amplification, a ballast laser signal is output through a substrate of the lasing SOA. This ballast laser signal is indicative of the output power of the lasing SOA. At least one detector converts the ballast laser signal to an electrical signal and transmits this electrical signal to a power monitor circuit. Using the electrical signal, the power monitor determines the output power of the lasing SOA. A pump control adjusts the rate at which the lasing SOA is pumped in order to change the saturation level of the lasing SOA and its corresponding power output ceiling. According to one embodiment, the power monitor identifies when the lasing SOA is approaching saturation or is saturated. If the lasing SOA is saturated or approaching saturation, the pump control increases its pumping rate causing the saturation level of the lasing SOA to rise. As a result, the lasing SOA is provided protection from saturation.

摘要： A broadband semiconductor optical amplifier (SOA) device includes at least two gain-clamped SOAs having different spectral responses. The gain-clamped SOAs are coupled so that the broadband SOA device has a spectral response which is not attainable by any one of the gain-clamped SOAs. The gain-clamped SOAs may be coupled in different ways. For example, they may be coupled in parallel, in series, or in another different and/or more complex ways. In one implementation, the gain-clamped SOAs are vertically lasing semiconductor optical amplifiers.
