Optical Transmission With Multiple Stages TRIZ Cases
- Erbium-Doped Fiber Amplifier With C-Band Noise Filtering
Broadband erbium-doped fiber amplification uses C-band filtering to improve SNR across S-, C-, and L-band optical signals.
- Photonic RF Steganography Using Dispersion-Matched Signal Recovery
Broadband ASE light and matched dispersion hide RF signals in optical noise, then recover them only at the intended receiver.
- Photonic Integrated Circuit With SOA Array for Chromatic Dispersion Compensation
Photonic integrated circuit with semiconductor optical amplifier array splits and recombines signals to perform chromatic dispersion compensation.
- Switchable Gain Optical Amplifier with Circulator and Dual Stages
A switchable gain optical amplifier uses a circulator to route signals between two amplifier stages for flexible power control.
