MRM (Micro Ring Modulator)

Notes: 

• 優點：
1. compact design suitable for SiPho.
2. 改變折射率→ 改變notch wavelength.
3. higher Q leads to considerable modulation.
• 缺點：
1. Phase and Amplitude 交纏在一起
2. Notch wavelength 需要溫度穩定.
3. Higher Q rings are desirable but 頻寬較低.
• 調變原理：Carrier injection/ depletion 進行順向偏壓/ 逆向偏壓.
