Abstract: An optical waveguide device for loss absorption, and a fabrication method thereof, are provided. The optical waveguide device for loss absorption includes: a substrate of a predetermined material; a lower cladding formed on the substrate; an optical waveguide formed on the lower cladding, and formed of a material having a refractive index greater than a refractive index of the lower cladding; an upper cladding formed so as to completely cover the optical waveguide; and an absorption layer formed of a material having refractive index greater than a refractive index of the upper cladding, and formed on the upper cladding to a thickness which can absorb a reflected or radiated optical signal. As described above, an absorption layer capable of absorbing light is formed in the waveguide device upon fabricating the optical waveguide, thus minimizing or removing loss due to reflection and radiation of an optical signal.

Abstract: A low-loss optically active device is provided by forming a lower clad layer using linear polymer on a substrate capable of transmitting ultraviolet (UV) light, forming a non-linear polymer core region of a waveguide region; forming a linear polymer core region on opposite sides of the non-linear core region, and forming an upper clad layer on the lower clad layer and linear and non-linear core regions of the waveguide region. The waveguide is formed using non-linear polymer only at the region where the non-linear effect such as optical modulation or optical switching occurs, and is formed using linear polymer at the remaining regions, thereby minimizing the overall waveguiding loss of the device.

Abstract: A multiwavelength, multistage optical amplifier, which can be arranged in a cascade, substantially increases the degree of automatic power control (APC), multiwavelength APC (MAPC), and multiwavelength automatic gain control (MAGC), for at least two wavelengths. The multiwavelength, multistage optical amplifier or amplifier cascade has at least two spectrally different gain media (GM), i.e. first and second GM, connected in series for amplifying a signal having at least two wavelengths, i.e. first and second wavelengths. The first GM may be aluminosilicate erbium doped fiber, the second GM may be germanosilicate erbium doped optical fiber. The gain at the first wavelength is smaller than the gain at the second wavelength, while the signal power at the first wavelength is larger than the signal power at the second one, and vice versa. This may automatically compensate for loss tilt. The gain media may be homogeneously broadened.
