Title: Man Seop Lee: Innovator in Optical Technology
Introduction
Man Seop Lee is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of optical technology, holding a total of 3 patents. His work focuses on enhancing the performance and sensitivity of optical receivers and signal generation.
Latest Patents
One of his latest patents is a burst mode optical receiver designed to maintain a constant signal amplitude. This innovative device can accurately detect optical signals of minimum amplitude by automatically controlling the gain of a pre-amplifier based on the amplitude of the input optical signal. The receiver improves its sensitivity by increasing the gain when the input signal has a small amplitude that meets its receiving sensitivity.
Another notable patent is for an apparatus that generates a Carrier-Suppressed Return-to-Zero (CS-RZ) signal. This apparatus includes a mixer, a Low Pass Filter (LPF), a driver amplifier, and a single external modulator. The mixer creates a modulator input by mixing data with a half clock signal, while the LPF band-limits this data into a low-frequency band. The driver amplifier then amplifies the modulator input, allowing the external modulator to generate a CS-RZ signal with inverted phases of adjacent pulses.
