Disclosed are a heterogeneously integrated optical modulator and a manufacturing method thereof. The modulator includes a substrate having a trench, an input waveguide disposed at one side of the trench, an output waveguide disposed at the other side of the trench, a first Mach-Zehnder interferometer including first branch waveguides disposed between the input waveguide and the output waveguide and a heater disposed on one of the first branch waveguides, and second Mach-Zehnder interferometers connected to each of the first branch waveguides.

Heterogeneously integrated optical modulator and manufacturing method thereof

A method and a system generate global path planning of a robot according to a node specification principle that is defined based on social norms for an indoor space using an indoor map to assist human-friendly navigation of the robot.

Method and system for specifying nodes for robot path planning

Disclosed is an optical transmitter module including a directly modulated laser transmitter based on a directly modulated laser (DML) and an arrayed waveguide grating (AWG) chip that is vertically polished. The directly modulated laser transmitter includes a directly modulated laser chip array including one or more directly modulated laser chips, an impedance matching circuit that allows each of the one or more directly modulated laser chips to operate at a critical speed of 100 Gbps per channel or higher, and a radio frequency-flexible printed circuit board (RF-FPCB) that transmits a radio frequency (RF) modulating signal to the directly modulated laser chip array. The arrayed waveguide grating chip includes an optical waveguides that transfer multi-channel optical signals and a wavelength multiplexer that multiplexes the multi-channel optical signals. The directly modulated laser transmitter and the arrayed waveguide grating chip are spaced apart from each other and are optically coupled in chip-to-chip.

Optical transmitter module

A notification (information) provision method and an apparatus for providing a user with the information received through a connection using a communication protocol available between two different electronic devices is provided. The method includes establishing a communication path with at least one other electronic device using a communication protocol, detecting, when a notification (information) is received, the current state of the electronic device, displaying, when the current state is a first mode, the notification (information), and transmitting, when the current state is a second mode, the notification (information) to the other electronic device through the communication path.

Method and apparatus for providing user with information received by electronic device

A method and an electronic device for controlling call-forwarding of the electronic device corresponding to first call address information is provided. The electronic device includes transmitting, to at least one of a server or a second electronic device corresponding to second call address information, a call-forwarding request to forward, to the electronic device, at least one of incoming calls or messages addressed to the second call address information of the second electronic device; and providing the at least one of the requested incoming calls or messages addressed to the second call address information.
