The sub-mount platform is made of silicon-based material and has first and second contact surfaces. The photoelectrical conversion component is disposed on the first contact surface. The lens is disposed on the second contact surface. The sub-mount platform is disposed on one side of the base. The first contact surface and second contact surface have therebetween a height difference, such that the photoelectrical conversion component matches the center of the lens. Further provided is a light receiving and emitting device including the light receiving and emitting module, a printed circuit board and a plurality of conducting wires. The conducting wires are electrically connected to the photoelectrical conversion component and printed circuit board. The conducting wires are disposed on at least two sides of the light receiving and emitting module.

Abstract: An optical fiber end securing structure and a method of securing an optical fiber end are introduced. The optical fiber end securing structure includes a stub component, a substrate and an adhesive component. The stub component is cylindrical. The stub component has axially a through hole for receiving an optical fiber. The substrate has a securing groove. Two walls of the securing groove extend in the axial direction of the stub component. The distance between the two walls is less than the diameter of the stub component in the radial direction. The outer circumferential surface of the stub component is in linear contact with apexes of the two walls. The adhesive component fills the securing groove and connects the securing groove and the stub component. Therefore, the optical fiber end securing structure and the method of securing an optical fiber end enable the optical fiber to undergo high-precision engagement.

Abstract: A terminal portion structure of an optical transmission element includes a light guiding component, glass protection layer and convex lens. The light guiding component includes a core and a cladding enclosing the core. The cladding is of a lower refractive index than the core, allowing light signals to be transmitted in the light guiding component by total internal reflection. The glass protection layer covers at least a terminal portion of the light guiding component. The convex lens is disposed on one side of the glass protection layer. The cross section of the terminal portion of the light guiding component tilts relative to the axial direction of the light guiding component. The optical axis of the convex lens is perpendicular to the axial direction of the light guiding component. The focal point of the convex lens is located at the cross section of the terminal portion of the core.

Abstract: The present disclosure illustrates a platform system for in vitro cell co-cultivation with automatic trapping function. The platform system aims to develop a bio-chip applied in cell culture systems, and has several features. The first feature is that this co-cultivation platform can construct a micro environment suitable for culture of various cells. The second feature is dynamic perfusion. The microfluidic system is used to dynamically replace the culture medium, in order to maintain an appropriate environment for the growth of cells. The third feature is the automatic trapping. The cells to be cultured can be trapped in a suitable location according to the flow resistance, so that the damaged on the cell caused by manual operation can be minimized.

Abstract: This invention provides a detecting device and a method for a passive optical network (PON), which includes: a laser device; a detector coupled to the laser device and generating an output signal at one of a first level when the laser device emits light and a second level when the laser device does not emit light; and a processor repeatedly detecting the output signal in a fixed period, and simultaneously counting a total number of changes that the output signal changes from the first level to the second level and the output signal changes from the second level to the first level so as to detect whether a light leakage occurs in the PON.
