摘要： An optical amplifier includes a multi-mode pump laser module, a multi-mode waveguide, a multi-mode to multiple single-mode fiber converter module and a plurality of single-mode cores. The multi-mode pump laser module emits pump light having a plurality of modes to the multi-mode fiber or waveguide. The multi-mode waveguide propagates the emitted pump light to the converter module. The converter module receives the pump light and distributes the pump light approximately uniformly to a plurality of single-mode cores.

摘要： Disclosed herein are various embodiments of an optical cross-connect switch in which optical beamforming is used to generate desired (e.g., technically beneficial) beam profiles at the beam-steering element of the switch. An example beam profile that can be generated in this manner is a substantially rectangular beam profile generated from an input optical beam having a substantially Gaussian beam profile. The use of rectangular beam profiles may be beneficial because such beam profiles can be used to increase the optical fill factor of the beam-steering element of the switch, thereby enabling the switch to have a higher number of optical ports and/or a lower cost per optical port than comparable conventional optical cross-connect switches. In an example embodiment, the disclosed optical cross-connect switch can be used to implement a wavelength-selective optical router.

摘要： We disclose a vertical-cavity surface-emitting laser (VCSEL) whose optical resonator can support multiple transverse resonator modes. The VCSEL has a plurality of electrodes that can apply individually controllable electrical currents to the active semiconductor region of the optical resonator and be configured to excite, e.g., a single selected transverse resonator mode or a desired linear combination of transverse resonator modes. In some embodiments, the VCSEL's optical resonator may have an effective lateral geometric shape that causes the excitable transverse resonator modes to correspond to the waveguide modes of a cylindrical optical fiber.
