本論文的主題是應用傅立葉轉換脈衝塑形技術以及光電毫米波發射器研究產生與接收啾頻毫米波。我們利用時域頻域映射轉換的基本概念產生及控制啾頻毫米波訊號。實驗系統中的關鍵元件之一為光電式毫米波發射器，偵測是使用兆赫時析光譜量測。此量測系統的雷射光源是中心波長為1560奈米的飛秒鎖模摻鉺光纖雷射。
此論文中提出了兩種頻率調變方式所產生的毫米波訊號。其一為線性啾頻毫米波。我們設計光譜的包絡曲線為高斯曲線，則產生的線性啾頻毫米波波形之包絡曲線亦為高斯曲線並且時間頻寬乘積為6.03。其二為階梯形啾頻毫米波。我們增加了塑形脈衝的數量並時間頻寬乘積可達到32.17。另外，其模擬結果與實驗結果十分相似。由實驗結果可知，經由合適的光譜設計，我們可以任意調控毫米波時域訊號的振幅與頻率。由於良好的頻率調控性，此方法可以有效的增強毫米波脈衝壓縮雷達系統的時間解析度。

We study chirped millimeter-wave (MMW) generation and detection using a photonic transmitter (PT) and the Fourier-transform pulse shaping technique. Utilizing the basic concepts of frequency-to-time mapping, we explore generation and control of the effects of chirped MMW. Experimentally, one of the key components is a W-band PT. We achieved coherent detection of the n MMW signal by the THz-time domain spectroscopic (THz-TDS) technique. The excitation and probing light is a mode-lock Er:doped fiber laser with a center wavelength of 1560nm.
In this thesis, we proposed and demonstrated two different kinds of frequency -modulated MMW signal. The first one is a linearly chirped MMW waveform. We design the envelope to be a Gaussian-like curve in the optical spectra of the excitation laser, the envelope curve of the generated linearly chirped MMW waveform is also a Gaussian-like curve. The time-bandwidth product is 6.03. The second one is the step chirped MMW waveform. We enhance the number of shaped pulses and the time-bandwidth product achieved to 32.17. In the mean time, we setup and demonstrate a mathematical simulation model. The simulation results agree with the experimental results. As shown the the experimental results, we can arbitrarily tune the amplitudes and frequencies of the time domain MMW waveform through suitable design of the optical spectrum of the exciting light. Further, this method can increase the time resolution of the MMW pulse compression radar system.
