中文摘要
現今通訊網路與雲端科技對頻寬使用已接近飽和,全光式的訊號處理機制(All Optical Signal Processing)勢必成為趨勢,因為光對光訊號的轉換以及訊號調變可以避免傳統電光或光電的方式會受到RC線路上的頻寬限制和電路上能量損耗,造成無法達到高速傳輸。相位調變好處是能在低功率下達成訊號轉換,結合全光方法能做到高速調變,利用光的干涉將相位差轉換成強度的差別,沒有額外電路的限制,藉此達到更大的消光比(extinction ratio, ER)以及訊雜比(signal-to-noise ratio, SNR)。
本論文主要是在探討場驅動型元件(field-driven device)的量子井(Quantum Well, QW)會對入射光產生很強的吸收,形成內建電場,藉以發生折射率變化和相位變化;以及結合Mach-Zehnder Interferometer(MZI)的原理做全光式的干涉系統分析。使用場驅型量子井元件是因為擁有低偏壓的操作即能產生高非線性之吸收變化,所以亦產生高非線性折射率變化的特性,當利用強光吸收以建立內部電場時,可以當作全光式良好的相位調變器(phase modulator),且體積小相較於其他相位調變器更容易積體化
本論文中在實驗部分利用直流以及電訊號轉換光訊號兩種方式相互驗證了量子侷限史塔克效應(Quantum Confined Stark Effect, QCSE),在電場操作下有很強的折射率變化。再者,利用全光訊號轉換搭配差分移相鍵控解調器(Differential Phase-Shift-Keying Demodulator, DPSK),藉由輸出的訊號三個強度位準計算訊號的相位差。實驗結果在長度為350um的量子井波導做10.7Gb/s訊號的的全光調變,輸出可以達到相位差140度。
Abstract
Nowadays, the development of fiber communication and cloud technology faces a large challenge due to the saturation of signal bandwidth, intriguing the interests for high speed all-optical signal processing in the near future. All-optical signal modulation can enable high speed operation without using traditional RC circuit limitation, reducing power consumption and increasing the flexibility of management in optical network applications. Through the phase modulation in optical signal processing, usage of optical wave interference could lead to large signal-to-noise ratio, high extinction ratio, and low basic power need. Therefore, it is important to study high efficient phase modulation.
In this work, based on quantum confined Stark effect (QCSE), the refractive index- and thus phase- change in quantum well device is studied and used for optical modulation. As an optical power near the bandgap is incident into QW to induce high optical absorption, the built-in electric field from photo-absorption carriers could induce highly nonlinear optical absorption change, thus leading to highly nonlinear optical refractive index change. By exciting another optical wave near the bandgap, the high-efficient phase modulator can thus be expected, leading to all optical modulation.
In my experiment, the direct characteristics of electro-to-optical conversion is first used to examine the refractive index change against with electric field. Through the differential phase-shift keyed (DPSK) demodulator, the optical-to-optical (OO) cross phase modulation can be made to analyze and characterize the phase variation in QW device. Using as short as 350-um long active waveguide, 140 degree phase change is demonstrated.
