This invention provides an all-optical transistor optical modulation system, its modulation method, and its applications. The all-optical transistor optical modulation system includes a pump source, a signal source, and a micro-ring modulator. The micro-ring modulator includes a micro-ring resonator and a van der Waals material. Pump light output from the pump source is incident on the van der Waals material from one side, generating resonant light absorption. Signal light output from the signal source is coupled into the micro-ring resonator and interacts with the van der Waals material, thereby modulating the signal light with the pump light. This invention utilizes the limited bandgap and resonant light absorption in the visible and near-infrared bands of van der Waals semiconductor materials, as well as the resonant characteristics of a silicon-based micro-ring resonator, to fabricate an all-optical modulation system with a simple structure, high modulation rate, and short response time. This enables rapid modulation of communication optical signals and allows for all-optical modulation of optical phase and / or amplitude.

The giant dipole, a collective state of coherent dipole coupling, offers significant potential for quantum computing applications. An example method for detecting a giant dipole in a material can include applying, to a material comprising dipoles configured to couple to one another via dipole-dipole coupling, an optical pulse having a polarization; and detecting the giant dipole in the material based on one or more of: a time evolution of an excited energy state associated with a population of the dipoles, an emission signal in measured photoluminescence data of the material, or one or more temporal correlations between a first photoemission data obtained from the material and a second photoemission data obtained from the material.

The present invention relates to a non-linear resonant-structure optical transistor operating at a single frequency, comprising a non-linear medium that amplifies a signal wave through inverse second-harmonic generation or inverse third-harmonic generation interaction with a second-harmonic wave or a third-harmonic wave, and being in an off state in which no output wave is present at a collector when only a pump wave is input into an emitter of the optical transistor, and being in an on state in which a signal wave is amplified and output to the collector when the pump wave is input into the emitter and the signal wave is input into a base, wherein an input wave at the base controls an input wave at the emitter so as to control the on-off state and intensity of the output wave at the collector, thereby simultaneously implementing amplification and switching of the optical signal. In this manner, the present invention provides an optical transistor operating with a single-frequency light wave, and an optical system comprising same.

Efficiently utilizing multiple optical fiber networks with different topologies. [Solution] A distributed computing system is provided that includes multiple nodes and multiple optical network lines. Each node includes multiple optical switches, multiple optical transistors, a data processing unit, and a network control unit. Each optical switch has a first port connected to an optical transistor and multiple second ports to which multiple optical paths connected to multiple optical network lines are connected, and the second port to which the first port is connected can be switched. The network control unit of each node simultaneously switches the connection state of the multiple optical switches when the aggregate communication currently being performed is completed.
