Latest Patents

Samuel Rubin holds a patent for "Wavelength tuning optimization of semiconductor lasers." This patent describes a method of characterizing a tunable semiconductor laser diode by varying the laser tuning currents of a section. It involves measuring the output power transmitted by the laser through a wavelength discriminating device (WDD). The method determines the currents needed to optimize the laser output within the passband of the WDD. By aligning the laser to the center of the passband, transmission is maximized. Notably, this alignment is performed relative to the spectral response curve of the WDD, eliminating the need to know the actual wavelength of either the laser or the WDD. The WDD can be a multiplexer, a demultiplexer, an optical filter, or even a complete communications channel. This innovation optimizes the performance of optical communications channels by fine-tuning the wavelength of the laser source.
