    摘要: Discloses is an optical coherence tomography (OCT) which uses an active mode-locking fiber laser in order to obtain image information of a sample. An imaging device in accordance with an embodiment comprises: a light source unit; a light separation unit; a reference unit; a diagnostic unit; a light coupling unit; and a signal processing unit. The imaging device removes a high-priced variable filter which has mechanical restrictions by directly delivering a modulation signal to a light source unit, so it can overcome mechanical restrictions and reduce costs.

    摘要: Disclosed are a continuous wave supercontinuum laser source resonator using low-priced multimode semiconductor lasers as pumping light and applying a rare-earth doped optical fiber and a Highly Nonlinear Dispersion Shifted Fiber (HNL-DSF) to a ring resonator structure to embody a continuous wave supercontinuum light source, and a medical diagnostic apparatus using the same. The resonator consists of a pump combiner for inputting pumping light into the resonator; a rare-earth doped optical fiber for receiving and converting the pumping light into seed light of a predetermined wavelength band; a Highly Nonlinear Dispersion Shifted Fiber (HNL-DSF) for converting the light converted by the rare-earth doped optical fiber and oscillating in the resonator into a continuous wave supercontinuum laser source; and a coupler for outputting the supercontinuum laser source generated from the Highly Nonlinear Dispersion Shifted Fiber (HNL-DSF). Accordingly, it is possible to embody a simple and inexpensive continuous wave supercontinuum laser source.

    摘要: The present invention relates to a method for manufacturing a two-dimensional polymer optical waveguide, which is used for manufacturing a two-dimensional optical waveguide through simplified processes using a single imprint original master. The method includes: replicating a pattern through a first hot-embossing process on a thermoplastic polymer sheet using a single original master; forming a buffer layer on the surface of the replicated pattern; manufacturing a polymer mold having a cladding pattern on the other side without a buffer layer through a second hot-embossing process using the original master; replicating a pattern by molding the polymer mold out of an elastic material and forming an upper elastic mold and a lower elastic mold by vertically separating the elastic material; and forming middle cladding using the upper and lower elastic molds, filling regions on and below the middle cladding with core resin patterns, and performing a curing process after stacking upper and lower cladding to form a two-dimensional optical waveguide.
