An optical coupler is provided for a passive coherent combination of fiber lasers/amplifiers. A plurality of optical fibers are arranged in a close-packed hexagonal array having 1+3n(n+1) fibers with (3/2)(n−n)+3 interferometrically dark fibers and (3/2)(n+3n)−2 light fibers, where n is an integer greater than or equal to 1. Each optical fiber has a first end and a second end. The plurality of optical fibers are fused together along a section of each optical fiber proximate the first end of each optical fiber to form a fused section having a fiber axis. The fused section of the plurality of optical fibers is tapered to form a tapered region. A facet is at an end of the fused section. The facet is disposed in a direction perpendicular to the fiber axis. The coherent pattern is highly stable against perturbation.

Method and system for transmitting optical clock signals and quantum key signals on a single optical channel. A multi-photon optical clock signal is received at an electro-optic switch at a first clock rate. The electro-optic switch may be configured for an interval defined by a second clock rate for generating a single photon quantum key signal. The multi-photon optical clock signal and the single photon quantum key signal are combined such that the single optical channel transmits the single photon quantum key signal at a first interval and the multi-photon optical clock signal at a second interval. The quantum key signal is transmitted from a transmitter at a first timing, and detected by a detector at a receiver. An output signal of the detector is sampled at a second timing that is delayed relative to the first timing for reducing quantum bit error rate.

In one of the embodiments, a dark channel array is provided which includes gain channels, each configured to emit an output beam from an output surface and to have a light wave propagating therethrough. It further includes a dark channel configured to emit an output beam from the output surface of the dark channel array and to have a light wave propagating in the dark channel, such that output beams from the plurality of gain channels are coherently coupled in phase with each other. The dark channel array is configured such that the dark channel captures a portion of the output beam from at least two of the plurality of gain channels by radiant coupling.

Presented is a method and system for phase locking a multi-stage parallel fiber amplifier. The method comprises receiving a signal beam from a first stage, in one path of the multi-stage fiber amplifier, onto a fiber that is pumped to produce a saturated signal beam that is then output to a second stage that outputs an amplified beam. A characteristic of the of the saturated signal beam is that its phase and amplitude do not substantially change based on the amplitude of the signal beam input onto the fiber. The method further detects a portion of the amplified beam to produce a phase indication of the amplified beam relative to amplified beams of the other paths of the multi-stage fiber amplifier. The method modulates the pump level of the first stage to control the phase of amplified beam, and further controls the phases of the other amplified beams of the other paths to phase lock the multi-stage parallel amplifier. The saturated signal beam reduces phase changes in the second stage that would be opposite to, and therefore counteract, the phase changes intentionally modulated in the first stage.

A multiple-fiber, stretched, fused and cleaved coupler designed to act as an output window to a fiber laser array or fiber-coupled laser array, in which the stretch, length and/or position of the fibers is chosen facilitate the in-phase oscillation of the lasers in the array. The in-phase oscillation of the lasers is facilitated by making one or more of the fibers interferometrically dark and having a different propagation constant than the other fibers. The other fibers, the interferometrically lit ones, are made to have fairly uniform intensity under the same collimated illumination.

Described is a system for adaptive calibration of a sensor of an inertial measurement unit. Following each sensor measurement, the system performs automatic calibration of a multi-axis sensor. A reliability of a current calibration is assessed. If the current calibration is reliable, then bias and scale factor values are updated according to the most recent sensor measurement, resulting in updated bias and scale factor values. If the current calibration is not reliable, then previous bias and scale factor values are used. The system causes automatic calibration of the multi-axis sensor using either the updated or previous bias and scale factor values.
