  • Patent number: 10466516
    Abstract: A laser system may include a laser source configured to generate a laser light beam, a beam stabilizer downstream from the laser light source, and an acousto-optic modulator (AOM). The AOM may include an acousto-optic medium configured to receive the laser light beam, and a phased array transducer including a plurality of electrodes coupled to the acousto-optic medium and configured to cause the acousto-optic medium to output a zero order laser light beam and a first order diffracted laser light beam. The system may further include a photodetector configured to receive a sampled laser light beam split from the zero order beam and generate a feedback signal associated therewith, and an RF driver configured to generate an RF drive signal to the phased array transducer electrodes so that noise is diverted to the first order diffracted laser light beam based upon the feedback signal.

  • Patent number: 10139699
    Abstract: A communications device may include a local device, a remote device, and a multi-mode optical fiber coupled between the local device and the remote device. The local device may include a local spatial optical mux/demux coupled to the multi-mode optical fiber and having first and second local optical outputs and first and second local optical inputs, and a local electro-optic E/O modulator coupled to the second local optical input. The remote device may include a remote spatial optical mux/demux coupled to the multi-mode optical fiber, and a remote E/O modulator configured to generate a modulated signal onto a first remote optical output based upon modulating the first optical carrier signal from a first remote optical input responsive to a radio frequency (RF) electrical input signal.
