    • To provide an optical wave guide that may be produced by reproduction method in easy and simple manner, and has a structure that prevents light signal in its inside from leaking out from core, and a method for producing the same optical wave guide. A concave slot for forming a core is formed on the upper surface of a cladding substrate. And on both sides of the concave slot, cavities are formed via flat portions. An ultraviolet ray hardening type transparent resin is applied onto the surface of the cladding substrate, thereafter the transparent resin is pressed by a stamper. At this moment, a core is formed in the concave slot and excessive transparent resin is pressed between the stamper and the flat portions flows into cavities, as a result, it is possible to make the transparent resin thin in a short time. Thereby, it is possible to make the transparent resin left on the flat portions into thickness and width enough to prevent light in the core from leaking out.
    • 本发明的目的在于提供一种能够简单且容易地通过再现方法制作的光波导,并且具有防止内部的光信号从芯体漏出的结构以及该光波导的制造方法。 用于形成芯的凹槽形成在包层基板的上表面上。 并且在凹槽的两侧,空腔通过平坦部分形成。 将紫外线硬化型透明树脂涂布到包层基底的表面上,然后用压模压制透明树脂。 此时,在凹槽中形成芯,并且在压模之间挤压过量的透明树脂,并且平坦部分流入腔中,结果,可以在短时间内使透明树脂变薄。 由此,可以使留在平坦部分上的透明树脂的厚度和宽度足以防止芯中的光泄漏。
