A method includes establishing at a first location first and second fiber arrays of fibers T and R, and establishing at a second location third and fourth fiber arrays of fibers T′ and R′. A trunk cable is then used to optically connect fibers T to fibers R′ and fibers R′ to fibers T to form first fiber pairs (T,R) where T=1 to (N/2) and R=[(N/2)+1] to N, and second fiber pairs (T′, R′), where T′=1′ to (N/2)′ and R′=[(N/2)+1]′ to N′, wherein N is an even number greater than 2.

摘要： The present invention provides a low-loss high-repetition-rate pulsed laser modulator comprising: a 2*2, 1:1 coupler; a light delay module; a 1*2, 1:1 coupler. The present invention can modulate a low-repetition-rate pulsed laser to be a high-repetition-rate pulsed laser. The basic principle is: one beam of low-repetition-rate pulsed laser can be divided into two beams with the same light intensity by a 1*2, 1:1 coupler; control the two beams of light to have an optical path difference so that when they are coupled into a 2*2, 1:1 coupler, a double pulse repetition rate can be obtained; In the same way, when the two beams of light from former 2*2, 1:1 coupler, with another different optical path difference are coupled into the next 2*2, 1:1 coupler, a double pulse repetition rate can be obtained again; when we obtain the repetition rate we need, a 1*2, 1:1 coupler instead is connected to couple the two beams of light into one beam with a double repetition rate.

摘要： A connected optical waveguide structure comprises n four-port optical couplers, where n is greater than one; and n waveguide loops, each loop having a corresponding perimeter; wherein each of the n perimeters is different from each of the other n−1 perimeters. In one embodiment, for any pair of the n loops, the ratio of the larger perimeter to the smaller perimeter is greater than five halves (5/2).
