摘要： Particular embodiments of the present disclosure relate systems and methods for evaluating visible light sources. According to one embodiment, a method of evaluating a visible light source including a semiconductor laser having a gain section, a wavelength selective section, and a phase section includes applying a gain drive signal to the gain section of the semiconductor laser at a gain modulation frequency, and applying a triangular wave drive signal to the wavelength selective section of the semiconductor laser at a wavelength selective modulation frequency that is greater than the gain modulation frequency. The light source emits a plurality of optical output pulses. Output power values of the optical output pulses at a selected wavelength are detected. The output power value of one or more selected output pulses is compared with an output power threshold value to generate an indication of whether the visible light source satisfies an output power specification.

摘要： A method is given for aligning an optical package comprising a laser, a wavelength conversion device, at least one adjustable optical component and at least one actuator. The adjustable optical component may be moved to a command position by applying a pulse width modulated signal to the actuator. The command position represents an optimized alignment of the laser and wavelength conversion device. The actual position of the adjustable may be measured by measuring an output of a position measuring circuit, which may measure the voltage amplitude of an oscillation in a resonator tank circuit during an “off” period of the pulse-width modulated signal. The resonator tank circuit may comprise a capacitive element electrically coupled to the electrically conductive coil. The pulse-width modulated signal may then be adjusted to compensate for any difference in the actual position and the command position of the adjustable optical component. Additional embodiments are disclosed and claimed.

摘要： Methods of optimizing optical alignment in an optical package are provided. In one embodiment, the optical package includes a laser diode, a wavelength conversion device, coupling optics positioned along an optical path extending from the laser diode to the wavelength conversion device, and one or more adaptive actuators. The method involves adjusting the optical alignment of the wavelength conversion device in a non-adaptive degree of freedom by referring to a thermally-dependent output intensity profile of the laser diode and a thermally-dependent coupling efficiency profile of the optical package. The adjustment in the non-adaptive degree of freedom is quantified such that, over a given operating temperature range of the optical package, portions of the coupling efficiency profile characterized by relatively low coupling efficiency offset portions of the output intensity profile characterized by relatively high laser output intensity and portions of the coupling efficiency profile characterized by relatively high coupling efficiency offset portions of the output intensity profile characterized by relatively low laser output intensity. Additional embodiments are disclosed and claimed.
