Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connections are formed between electronic integrated circuits and photonic integrated circuits, then communication capabilities are enhanced, but manufacturing complexity and difficulty increase
Solution Approach 1:
The optical receiver is segmented into distinct functional modules: an optical demultiplexer that separates incoming optical signals into multiple wavelength channels, and multiple photodetectors that independently detect each separated signal. This modular segmentation simplifies the overall manufacturing process while enabling enhanced communication capabilities through parallel signal processing.
Solution Approach 2:
An optical demultiplexer is introduced as an intermediary component between the optical fiber input and the photodetector array. This intermediary device separates multiplexed optical signals into individual wavelength components, enabling each photodetector to process specific wavelength ranges independently, thereby simplifying the connection architecture between electronic and photonic circuits.
2Productivity
If optical signals are transmitted between EICs and PICs, then data transmission efficiency improves, but signal separation and reception difficulty increases
Solution Approach 1:
The incoming optical signal is segmented by the optical demultiplexer into multiple separated optical signals corresponding to different wavelength channels. Each separated signal is then directed to dedicated photodetectors, transforming the complex task of detecting multiplexed signals into simpler independent detection tasks, thereby improving data transmission efficiency while reducing detection difficulty.
Solution Approach 2:
Each photodetector is optimized with specific local properties to detect particular wavelength ranges or polarization states. The first photodetector is configured to receive the first separated optical signal while the second photodetector is configured for the second separated optical signal, enabling specialized local detection that simplifies the overall signal separation process.
