Abstract:
The technical background of the present invention relates to a semiconductor package and a semiconductor device including the same. The semiconductor package includes a package substrate; multiple connection devices on the package substrate; a semiconductor chip including at least one optical I/O device, which transmits and receives optical signals in a direction skewed from the vertical direction of the lower surface of the package substrate by an optical I/O angle, and electrically connected to the package substrate through the multiple connection device.
Abstract:
An optical memory system includes a plurality of memory modules and an optical distributing part. A light source generates light. The memory modules include a plurality of memory devices respectively. Each of the memory module outputs an optical signal to a memory controller by converting an electric signal outputted from the memory devices into the optical signal by using the light generated by the light source. The optical distributing part is connected between the light source and the memory modules and distributes the light to the memory modules.
Abstract:
PURPOSE: A 3D image sensor is provided to polarize received light reflected from a subject, thereby reducing interference effects due to external light. CONSTITUTION: A light source module(300) irradiates transmitting light onto a subject. A lens module(400) polarizes the received light, which is reflected from the subject, by the transmitting light. The lens module provides the polarized received light. A sensing unit(100) converts the polarized received light into electrical signals.
Abstract:
PURPOSE: An optical modulator with reduced size and an optical transmitter having the same are provided to implement miniaturization by removing the use of a passive component and to implement a magh zender type modulator. CONSTITUTION: An optical input unit divides an input optical signal into a first optical signal and a second optical signal. A phase shifter(130) is located in a first path or a second path. The phase shifter modulates the first optical signal or the second optical signal. An optical output unit generates an output optical signal by combination of signals.
