▎ 摘　　要

NOVELTY - The device has a laser radar emitting chip (7) whose bottom end is provided with a thermistor. A bottom end of the thermistor is paved with an upper electrode sheet. Bottom ends of an electric connecting wire (3) are provided with bridge-shaped magnetic brackets that are arranged on a surface liquid of a metal radiating micro-channel (4) in a bridge-shaped structure. A tail end of a waveguide is connected with a grating antenna for diffracting a light beam to a free space to realize beam steering. A grating coupler receives external light source and incident light coupling to single-path transmission light. A waveguide transmits an optical signal. A multi-path waveguide generates uniform phase difference. A grating antenna is used for diffracting the light beam to free space for realizing beam steering. USE - Full solid-state laser radar optical power amplifier (OPA) emitting chip device based on electromagnetic heat controlling. ADVANTAGE - The device has stable heat tuning, good radiating performance and low optical signal loss based on electromagnetic control heat. The device quickly drives the conducting heat of the fin-shaped graphene cooler, so as to quickly reduce the temperature of the work piece, thus ensuring the stability of the optical signal heat tuning. The heat in the shell is prevented from gathering, at the same time, the large porosity between the graphene molecules and the thermal conductivity are used for improving the radiating performances of the chip, effectively solving the problem that the power density caused by the doubled integration of the semiconductor integrated circuit is increased, thus causing temperature rise increasing problem, and the heat flow is transited to the lower end of the thick and short in the elongated upper end the laser radar emitting chip has buffer transition, avoiding the sudden temperature difference increasing chip DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the Full solid-state laser radar OPA emitting chip device based on electromagnetic heat controlling.
