Abstract: An in-fiber wavelength division multiplexing method and a device for emitting multi-channel optical signals are provided to improve a coupling coefficient of a WDM device by totally reflecting multiplexed optical signals from a Bragg lattice. A WDM(Wavelength Division Multiplexing) device includes a core(110) and a cladding(120). The core delivers multi-channel optical signals and includes an optical fiber Bragg lattice(130), which multiplexes the multi-channel optical signals. The cladding encloses the core and includes a V-groove like etching cladding(121), so that the multi-channel optical signals from the Bragg lattice are totally reflected to the outside. The Bragg lattice is slantingly arranged. The Bragg lattice multiplexes forward directional multi-channel optical signals, which are received from the core. The Bragg lattice couples the multiplexer multi-channel optical signals with a reverse directional optical fiber cladding mode.

Abstract: An optical fiber for optical signal out-coupling and an optical signal detecting device using the same optical fiber are provided to facilitate production work due to a simple structure and to package the optical fiber manually by forming a V-groove at the predetermined position of a cladding part. An optical fiber(100) for optical signal out-coupling consists of a core(110) having a tilted bragg grating(112) or a long period fiber grating and a cladding(120) covering the core and having at least one V-groove(122,124). The optical fiber out-couples an optical signal by using the bragg and the V-groove. If the tilted bragg grating is formed at the core, the tilted bragg grating combines a forward core mode as a reverse cladding mode. If the long period fiber grating is formed at the core, the long period fiber grating combines a forward core mode as a forward cladding mode.
