【摘要】：提出一種基于光學可調色散的三角波信號光學產(chǎn)生方案,并進行了實驗驗證。本振信號驅動雙電極Mach-Zehnder調制器(DE-MZM)的一臂,對連續(xù)波(CW)激光進行調制,產(chǎn)生各階光邊帶,通過合理設置DE-MZM的直流偏壓點,并利用可調色散補償器(TDC)對光信號引入一定的移相,光電探測后可以得到與本振(LO,local oscillator)信號重復率相等的三角波信號。通過簡單地改變LO信號頻率,得到的三角波信號重復率也相應發(fā)生變化。在實驗中,利用本文方案分別得到了重復率為5GHz和6GHz的三角波信號。本文方案結構簡單,頻率調諧靈活,利用現(xiàn)有商用光電器件,預期能夠得到重復率高達40GHz的三角波信號,可滿足未來高頻電子系統(tǒng)的應用需求。
[Abstract]:An optical generation scheme for triangular wave signals based on optical adjustable dispersion is proposed and verified by experiments. The local oscillator signals drive one arm of the two-electrode Mach-Zehnder modulator DE-MZM, and modulate the CW CW laser to produce each order optical sideband. By reasonably setting the DC bias point of the DE-MZM, and using the adjustable dispersion compensator to introduce a certain phase shift to the optical signal, The triangular wave signal with the same repetition rate as the local oscillator signal can be obtained by photoelectric detection. By simply changing the frequency of Lo signal, the repetition rate of triangle wave signal is changed accordingly. In the experiment, the triangle wave signals with repetition rate of 5GHz and 6GHz are obtained by using the scheme in this paper. In this paper, the scheme is simple, the frequency tuning is flexible, and the triangle wave signal with repetition rate up to 40GHz can be obtained by using the existing commercial optoelectronic devices, which can meet the application needs of the future high-frequency electronic system.
