    Abstract: An optical device includes: a waveguide array including a plurality of waveguides; and a pulse generator. The waveguides are arranged in a first direction and extend in a second direction intersecting the first direction. The pulse generator inputs, as an input light beam, a light pulse of light to each of the waveguides. The light has a frequency spectrum in air with a maximum peak at a frequency corresponding to a wavelength λ, and the full width at half maximum of the maximum peak is Δν. The waveguides propagate the input light beams in the second direction and emit part of the input light beams as emission light. The pulse generator adjusts the difference in phase between input light beams to be inputted to two adjacent waveguides of the plurality of waveguides to thereby change a first direction component of an emission direction of the emission light.

    Abstract: A projector includes a light source unit, a spatial light modulator configured to control light from the light source unit for each pixel to form an optical image, and a projection optical system configured to project the optical image formed by the spatial light modulator onto a target. The light source unit includes a solid-state light source and a wavelength convertor. The solid-state light source is configured to emit first light, the first light including blue light with a peak wavelength in a range of 430 to 470 nm, inclusive, and green light with a peak wavelength in a range of 480 to 550 nm, inclusive. The wavelength convertor contains a red phosphor including Ce as a luminescent center that is configured to emit second light upon receiving the green light. The second light has a spectrum with a peak wavelength of 600 to 700 nm, inclusive. The red phosphor contains a nitride or an oxynitride as a host material.

    Abstract: An optical scanning system including an optical scanning device, and a photoreceiver device. The optical scanning device includes: a first waveguide array including a plurality of first waveguides; and a first phase shifter for adjusting phases of light propagating through the plurality of first waveguides to change an emission direction of emission light from the plurality of first waveguides. The photoreceiver device includes: a second waveguide array including a plurality of second waveguides configured to receive reflected light and propagate the received reflected light; and a second phase shifter for adjusting phases of the received reflected light propagating through the plurality of second waveguides to change a reception direction of the reflected light received by the plurality of second waveguides. An array pitch of the plurality of first waveguides in the optical scanning device differs from an array pitch of the plurality of second waveguides in the photoreceiver device.
