Abstract: PURPOSE: To make a reception side system compact and inexpensive in an optical fiber communication of a multiple wavelength transmission system by a method wherein light signals of multiplexed wavelengths are separated from each other in every wavelength by a single element to convert into an electrical signal by a simple constitution and without exercising a complicated control. CONSTITUTION: A plurality of diode parts α and β, which respectively have light absorption layers 5 and 11 having also combinedly function which acts as the function of an optical waveguide, are arranged in a state that they are insulated from each other so that each light absorption layer is arranged on an optical path. Moreover, the diode parts are formed so that the compositions of the layers 5 and 7 of each diode part are made to differ from each other and the layers 5 and 11 have band gap wavelengths different from each other.  When signal lights pass through in order the light absorption layers of each diode part, the signal lights only of the wavelengths within the range of the band gap wavelengths of the light absorption layers are made an O/E conversion in the diode part and the signal lights of wavelengths, which are out of the range, are propagated to the following diode part. Such the O/E conversions are made in order and the light signals of the multiplexed wavelengths are respectively converted into an electrical signal.

Filed: 1986-08-13
Abstract: A low loss fiber optic coupler is fabricated by forming a coupler preform (10) having a plurality of spaced glass cores (12,13) extending longitudinally through a matrix of glass having a refractive index lower than that of the cores. The preform is heated and stretched to form a glass rod (20) which is then severed into a plurality of units (21). Heat is applied to the central region (23) of each unit while the ends of the unit are pulled apart to elongate the taper inwardly the heated central region. The unit is then provided with a plurality of optical fibers (69, 70, 75, 76°, 82, 83; 89), one of which extends from each of the cores at the endfaces of the unit. A preferred method of providing the optical fibers involves forming the coupler preform of a matrix glass (46) that is easily dissolves in a solvent. Each of the fiber cores within the matrix is surrounded by a layer of cladding glass (54) that is relatively resistant to disolving by the solvent.
