摘要： 250 μm is the standardized pitch H of the prevalent multichannel ribbonfibers. Current laser diodes and photodiodes have a size larger than 300 μm. Curving lightpaths made on a silicon bench for reconciling the chip size with current ribbonfibers causes bending power loss, optical crosstalk and difficulty of production. Linear parallel lightpaths with a width d for more than one chip site are produced on a bench with a pitch E which is equal to the pitch H of the multichannels. Optoelectronic device chips with a width W satisfying an inequality E

摘要： A multichannel parallel LD/PD module comprising a bench, a plurality of lightpaths having an initial narrow width region, an intermediate width enlarging region and a final wide width region, a plurality of photodiodes or a photodiode array mounted on the narrow width region, a wavelength selective filter formed on the narrow width region for selectively reflecting receiving beams, a plurality of light emitting devices fitted behind rear ends of the lightpaths on the bench. Traveling in element fibers in an outer ribbon fiber, receiving signal beams go into the lightpaths via front ends and are reflected by the wavelength selective filter slantingly upward at the narrow width region. The reflected beams go into the photodiodes and are converted into photocurrents in proportion to the receiving signals. Emanating from the light emitting devices, transmitting signal beams enter the lightpaths via final ends of the wide width region, propagate backward in the width enlarging region, arrive at the narrow width region, transfer to outer element fibers in a connector, and propagate in the ribbon fiber following the connector. Long distances between the transmitting portion (LDs or LEDs) and the receiving portion (PDs) suppress optical, electromagnetic and electric crosstalk between the light emitting devices and the photodiodes.

摘要： An optical transceiver module comprises a submodule having a Y-branching optical transmission line formed on a flat platform such that a leading end is exposed at the front surface and having an LD chip and a PD chip disposed at first and second trailing ends of the optical waveguide. The submodule is secured to the front surface of a pole of a metal stem, and a condenser lens and an end of an optical fiber are secured relative to the stem by a metal package member so that the optical fiber and the leading end of an optical waveguide can be optically coupled by the condenser lens. Transmission light from the LD is focused by the lens and can be sent out to the optical fiber, and reception light that has propagated through the optical fiber can be received by the PD. Thus, the optical transceiver module whose submodule is accommodated in a metal package is superior in reliability, durability, and airtightness.
