Field-induced guide/antiguide modulators on InGaAsP/InP (original) (raw)

Field-induced guide/antiguide modulators (FIGAMs) on InGaAsP/InP are introduced as high-performance optical devices that provide significant advantages over conventional modulators. The paper discusses the fabrication and design of these modulators, highlighting their high on/off ratios, broad optical bandwidth, and compatibility with photonic integrated circuits. Key findings reveal that through optimized electrode configuration and waveguide design, low excess losses can be achieved, making FIGAMs promising for applications in long-wavelength optical fiber communications.
