A Novel Optical Direct-Detection I/Q Up-Conversion with I/Q Imbalance Compensation via Gram-Schmidt Orthogonalization Procedure
Novel Optical I/Q Imbalance Compensation Gram-Schmidt Orthogonalization Procedure
2015/7/20
We proposed RF detect-detection vector signal generation using optical I/Q up-conversion. The Gram–Schmidt orthogonalization procedure is employed to compensate I/Q imbalance. After transmission over ...
Novel Optical 90o Hybrid with Low Wavelength Sensitive Power Balance and Phase Deviation over 94-nm-wide Spectral Range
Novel Optical Wavelength Sensitive Power Balance Phase Deviation Spectral Range
2015/7/14
We propose a novel optical 90o hybrid employing a paired-interference 2×4 MMI coupler where no waveguide intersection in coupling to photo detectors is required. The proposed device exhibited 90o hybr...
