摘要： A system for generating and detecting terahertz radiation comprises a first laser (1) and a second laser (2), each having a different frequency of laser light output. The system further comprises a radiation generating stage (4, 9) arranged to generate terahertz radiation by beating the light output of the first laser (1) with the light output of the second laser (2). A radiation detecting stage (12) is arranged to modulate light output from the first laser (1) with received terahertz radiation.

摘要： A multiwavelength transmitter comprises several laser sources (1) each configured to generate light of a different wavelength and a first array waveguide grating (2) arranged to direct light from each of the laser sources (1) into a first waveguide. The transmitter further comprises several electroabsorption modulators (7) each arranged to modulate light at one of the wavelengths with a respective data signal and a second array waveguide grating (6) arranged to direct each of said different wavelengths of light from the first waveguide to a respective one of the modulators (7). The optical modulators (7) are reflective optical modulators and the second array waveguide grating (6) is arranged to direct the modulated light reflected from each of the optical modulators (7) back into the first waveguide. An optical circulator (5) is provided in the first waveguide to couple modulated light from the second array waveguide grating (6) into an output waveguide. The laser sources each comprise a respective reflective semiconductor optical amplifier (1) and share a common cavity reflector (3). The first array waveguide grating (2) is located in the optical path between the semiconductor optical amplifiers (1) and the common cavity reflector (3). The transmitter has the advantage that it can be manufactured by hybrid integration of a monolithic wavelength generation sub-module and a monolithic data modulation sub-module.

摘要： An electroabsorption modulator comprises an absorption layer (1) between two layers of n-doped semiconductor (2, 5). The absorption layer (1) is doped or implanted with Fe ions making it semi-insulating. The use of an NiN structure rather than a PiN structure significantly reduces the series resistance of the device. The Fe-doping of the absorption layer reduces the leakage current of the NiN structure and provides recombination sites for hoto-generated electron-hole airs.
