Controllable terahertz wave power splitter with variable output ports

Abstract

The invention discloses a controllable terahertz wave power splitter with variable output ports. The power splitter comprises dielectric cylinder photonic crystals in two-dimensionally periodic arrangement; the power splitter further comprises a first control signal input end, a second control signal input end, a first signal input end, a second signal input end, a first signal output end, a second signal output end, a first photonic crystal resonance ring, a second photonic crystal resonance ring, a third photonic crystal resonance ring, a fourth photonic crystal resonant ring, a first coupled photonic crystal dielectric cylinder array, a second coupled photonic crystal dielectric cylinder array, a third coupled photonic crystal dielectric cylinder array, a fourth coupled photonic crystaldielectric cylinder array, a fifth coupled photonic crystal dielectric cylinder array, a sixth coupled photonic crystal dielectric cylinder array, a seventh coupled photonic crystal dielectric cylinder array and an eighth coupled photonic crystal dielectric cylinder array which are located among the dielectric cylinder photonic crystals. When the first control signal input end and the second control signal input end continuously input control signals, by selecting different signal input ends for inputting terahertz wave signals, terahertz waves are controlled to be output from different signal output ends, and the controllable terahertz wave power splitter with the variable output ports is achieved. The controllable terahertz wave power splitter with the variable output ports has the advantages of being simple in structure, controllable, small in size, low in cost, easy to integrate and the like.

Description

technical field [0001] The invention relates to a power splitter, in particular to a controllable terahertz wave power splitter with variable output port. Background technique [0002] Terahertz radiation is located between microwave and infrared radiation in the electromagnetic spectrum. The name of terahertz radiation comes from its oscillation frequency of about 0.1~10THz. In the field of electronics, electromagnetic waves in this frequency band are related to millimeter waves and submillimeter waves. In the field of spectroscopy, its frequency band coincides with far-infrared rays. For a long time, due to the lack of high-energy, high-efficiency, terahertz radiation sources that operate stably at room temperature and effective terahertz wave detection technology, compared with the well-developed microwave technology and optical technology, terahertz technology and related application research Progress is very slow, and the terahertz band has become the only wave band th...
