Abstract :
The effect of a matching or sealing layer inserted in the coupling region of a lapped fiber coupler is analyzed. It is found that the first-order correction factor to the coupling coefficient is proportional to the optical path increment but is independent from bending radius and fiber separation. Specific data with reference to wavelength division multiplexing couplers are presented.<>
