Abstract: The present application provides an optical device and a method of fabricating the same. The optical device include a semiconductor stack structure, an anti-reflective film and a highly-reflective film. The semiconductor stack structure is configured to generate a laser beam and emit the laser beam from its front facet while receiving an electric current. The anti-reflective film is disposed on the front facet of the semiconductor stack structure and configured to increase the transmittance (reduce a reflectivity) of the front facet to the laser beam. The highly-reflective film is disposed on a rear facet of the semiconductor stack structure and is configured to reduce a loss (increase a reflectivity) of the laser beam transmitted to the rear facet. The anti-reflective film and the highly-reflective film respectively have refractive indices greater than 2, and the highly-reflective film has a thickness greater than that of the anti-reflective film.

Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: An antenna module includes two antenna units, two isolation members, and a grounding member. Each antenna unit consists of two feeding ends, two first radiators, and two second radiators. The isolating members are disposed between the first and second portions of each antenna unit. The grounding member is disposed beside the two antenna units and the two isolation members. A first slot is formed among each first radiator, the second radiator, and the grounding member. The two second radiators are connected to the third radiator. A third slot is formed between the second radiator and the second portion. The two antenna units are symmetric to the fourth slot in a mirrored manner, and the two first portions have widths gradually changing along an extending direction of the fourth position.

Abstract: A miniature cooling system includes a base metal sheet, a flow channel layer, a piezoelectrically actuated metal sheet, a piezoelectric boundary compression layer and two piezoelectric ceramic vibrators. The flow channel layer is located on the base metal sheet and includes a first chamber, a second chamber, an inlet channel, a linking channel and an outlet channel. The inlet channel links the outside environment to the first chamber. The linking channel links the first chamber and the second chamber. The outlet channel links the second chamber to the outside environment. The piezoelectrically actuated metal sheet is located on the flow channel layer. The piezoelectric boundary compression layer is located on the piezoelectrically actuated metal sheet. The piezoelectric boundary compression layer includes two containing areas, and the two containing areas are respectively located above the first chamber and the second chamber.

Abstract: A linear piezoelectric motor and a slider drive system thereof are disclosed. The linear piezoelectric motor includes a piezoelectric ceramic element and a base structure. The piezoelectric ceramic element includes a first region, a second region and an interval region located between the first and the second region, wherein the first and the second region may be formed by a first and a second power signal supplied by a power supply to form a first and a second standing wave, respectively. The interval region is a quarter wavelengths. The first and the second standing wave have a phase difference so as to form a traveling wave. The base structure disposes the piezoelectric ceramic element and has a pectinate structure to increase the amplitude of the first and the second standing wave, thereby enabling the piezoelectric motor to be driven.
