Abstract: Provided is a distance measuring device and a method of measuring a distance. The distance measuring device detects light reflected by an object, generates an electrical signal based on the detected light, detects whether the electrical signal is saturated or not by comparing the electrical signal with a reference value, controls a magnitude of the electrical signal based on whether the signal is saturated, and calculates a distance to the object using the electrical signal.

Abstract: An optical modulator may include an optical wave guide configured to allow a light to pass therethrough, and an optical modulating layer embedded in the optical wave guide and configured to modulate a phase of the light. The optical wave guide may include a first material that has a first lattice constant. The optical modulating layer may include a second material that has a second lattice constant different from the first lattice constant. The phase of the light may be modulated by the optical modulating layer based on a difference between the first lattice constant and the second lattice constant.
