Abstract
A method and apparatus are provided. The method includes receiving, at a TEmode add/drop filter, a TEmode optical signal having a first wavelength and a second wavelength, and transmitting, from the TEmode add/drop filter, the TEmode optical signal having the first wavelength and the second wavelength towards a Bragg grating, without converting the TEmode optical signal having the first wavelength and the second wavelength to another mode. The method further includes receiving, at the TEmode add/drop filter, a reflected TEmode optical signal having the first wavelength from the Bragg grating, and transmitting, from the TEmode add/drop filter, the reflected TEmode optical signal having the first wavelength towards a photodetector, without converting the reflected TEmode optical signal having the first wavelength to another mode.
