摘要： Disclosed are a broadband light source and a method of fabricating the same. The method includes the steps of forming a lower clad on a substrate, forming an active layer having a multiple well structure on the lower clad (so as to generate light having a broad wavelength band), sequentially depositing an upper clad and a cap on the active layer, depositing a cover layer including at least two regions having bandgaps different from each other on the cap, and heat-treating the broadband light source including the cover layer.

摘要： A light source driving circuit and method is provided. The light source driving circuit includes a light source for outputting light, a light receiving unit for detecting a portion of the light output from the light source, a switching unit for controlling the supply of a source voltage according to an operation control signal, a constant current source for supplying a current corresponding to a threshold current to the light source according to the control of the switching unit, and an automatic power controller for controlling a driving current of the light source in response to an external modulation signal. Accordingly, by supplying a current corresponding to a threshold current of a green laser by means of a switching operation according to an operation control signal for a set time before a modulation signal of the green laser is input, a turn-on delay of the green laser can be reduced.

摘要： Disclosed is a method of reducing speckles appearing in a laser beam. The method includes the steps of splitting the laser beam into two polarized light modes perpendicular to each other; modifying the phase of at least one of the two polarized light modes, and combining the two polarized light modes into a single laser beam outputted. The method is performed by using an apparatus that includes a light source to generate a laser beam, a polarization split filter to split the laser beam into two polarized light modes perpendicular to each other and then re-combine said two polarized light modes, and a multi-angle reflection mirror to reflect one of the two polarized light modes to the polarization split filter, wherein the polarization split filter is inserted in the multi-angle reflection mirror.
