    摘要: Systems, and apparatus for adding reflection based pre-emphasis to a laser driver. In one aspect, a device includes a load (e.g. a laser) having a load impedance, a first end of a transmission line connected to the load, and a reflective impedance element connected to a second end of the transmission line. The reflective impedance element has a given impedance value that differs from the transmission line's characteristic impedance, and the characteristic impedance differs from the load impedance. This mismatch causes reflections between the reflective impedance element and the load. The reflections between the reflective impedance element and the load combine with an incident signal at the load to create a target signal having a target spectral shape.

    摘要: A solid-state lighting device includes a light source section, a light emitting section, a light receiving section, a light guiding section, and a protection circuit. The light source section has a semiconductor laser including a light emitting layer made of nitride, and a driving circuit. The light source section emits laser light having a wavelength range from bluish purple to blue. The light emitting section includes a heat conduction part which includes a wavelength conversion layer absorbs the laser light and emits wavelength-converted light, and an optical part which is capable of guiding the laser light. The light receiving section is capable of detecting returning light from the optical part. The light guiding section guides the laser light from the light source section toward the optical part, and guides returning light from the optical part toward the light receiving section. The protection circuit outputs a driving stop signal toward the driving circuit if it is detected that amount of the returning light is not included in a prescribed range using an electrical signal output from the light receiving section. The driving circuit stops driving the semiconductor laser if the driving stop signal is input.
