“…Power equalization is possible by adjusting the driving voltages of each pixel. The variation can be less than 0.5 dB, as demonstrated in our recent work [13]. By using an optical spectrum analyzer with a spectral resolution of 0.01 nm, we have determined that the output central wavelength of the laser by turning on the LCPM pixels is within ± 0.02 nm (± 2.5 GHz) of the ITU grid.…”

We report a novel external cavity laser diode (lambda= 1.5 mum). An intra-cavity liquid crystal pixel mirror allows digitally tuning of the laser wavelength to more than 40 wavelength channels of 100 GHz spacing according to the International Telecommunication Union (ITU) grid. Laser wavelength can further be fine-tuned by varying the driving voltages applied to an intra-cavity planar nematic liquid crystal phase plate. With a cell 52.3 mum in thickness, the output frequency can be continuously tuned over 1.89 GHz. The root-mean-square voltage required for driving the phase plate was from 1.00 to 4.56 volts.
