TLDR
Biconically tapered fiber-optic star couplers with up to 100 fiber channels were reported in this paper. But the insertion losses were not as low as −0.56 dB and the normalised standard deviations of output poers as high as 4.4%.Abstract:
Biconically tapered fibre-optic star couplers with up to 100 fibre channels are reported which have excess insertion losses as low as −0.56 dB and normalised standard deviations of output poers as low as 4.4%read more

Analysis of a tunable single mode optical fiber coupler
Michel J. F. Digonnet,H.J. Shaw +1 more
TL;DR: In this article, the authors report the operation and theoretical modeling of an efficient, tunable, and low-loss single-mode fiber coupler, which can be tuned to achieve up to 100 percent coupling ratio and 50 dB extinction ratio between coupled and direct branches.

Coupled modes of multiwaveguide systems and phased arrays
A. Hardy,W. Streifer +1 more
TL;DR: In this paper, a new theory describing coupled mode propagation in an array of arbitrary optical waveguides is developed, which unambiguously accounts for real and/or imaginary index perturbations and its solutions yield supermode patterns and propagation constants.

Coupled mode solutions of multiwaveguide systems
Amos A. Hardy,W. Streifer +1 more
TL;DR: In this paper, a coupled mode formulation for guided wave propagation in an array of N -parallel waveguides is presented and the resulting matrix differential equations are solved for two-and three-waveguide systems.

Optical star coupler and method for manufacturing the same
TL;DR: In this paper, a biconically tapered optical star coupler is inserted into a protection tube such as hollow glass tube, then the optical fiber bundle is twisted and pulled while it is indirectly heated through the protection tube, thereby to form a twisting, fusing and pulling portion, and both ends of the protected tube are sealed with an adhesive agent to fix the optical fibre bundle to the protection tubes.
