OPTICAL MODULATING DEVICE AND APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17699553 titled 'OPTICAL MODULATING DEVICE AND APPARATUS INCLUDING THE SAME
Simplified Explanation
The patent application describes an optical modulating device that includes a substrate with trenches, a phase modulator, an amplifier, and an insulating layer.
- The phase modulator is located between the trenches and consists of an undoped region with doped regions on either side. It modulates the phase of light passing through the undoped region based on an electrical signal.
- The amplifier is positioned on top of the substrate and overlaps with the phase modulator. It includes doped layers, a quantum well layer, and a clad layer. The amplifier amplifies the light based on an electrical signal.
- An insulating layer is placed between the phase modulator and the amplifier to provide electrical isolation.
Potential applications of this technology:
- Optical communication systems
- Fiber optic networks
- Optical signal processing
Problems solved by this technology:
- Efficient modulation of light phase
- Amplification of light signals
- Electrical isolation between the phase modulator and amplifier
Benefits of this technology:
- Improved performance of optical modulating devices
- Enhanced signal processing capabilities
- Increased efficiency in optical communication systems
Original Abstract Submitted
Provided is an optical modulating device including a substrate including first and second trenches, a phase modulator in a region of the substrate, the phase modulator including an undoped region provided between the first and the second trenches, and first and a second doped regions which are apart from each other with the undoped region therebetween, wherein the phase modulator is configured to modulate a phase of light traveling through the undoped region based on a first electrical signal applied to the phase modulator, an amplifier including a first doped layer, a quantum well layer, a clad layer, and a second doped layer sequentially on the substrate, the amplifier overlapping at least a portion of the phase modulator and being configured to amplify the light based on a second electrical signal applied to the amplifier, and an insulating layer between the phase modulator and the amplifier.
