    Abstract: An apparatus comprising a visible light source(s), multimode optical fiber(s), light coupler(s), an optional spatial light modulator(s), and an optional projection lens(es). The light source has a 1/e half-width emission bandwidth. The light coupler couples the light source to the multimode optical fiber(s) such that objective speckle contrast is reduced. The multimode optical fiber(s) may pass light from the coupler to an optional spatial light modulator. The spatial light modulator may modulate the light to form an image. The projection lens may transfer light onto an image plane or to illuminate objects. The objective speckle contrast at the end of the multimode fiber in combination with the projection lens diameter (if employed) and wavelength diversity may result in viewed images at the viewer's eye, or other detector, exhibiting speckle contrast that may be 1% or less.

    Abstract: The invention provides a semiconductor optical modulator including a two-step mesa optical waveguide having a first clad layer (101); a mesa-like core layer (102) formed over the first clad layer (101); and a second clad layer (103) formed into a mesa shape over the core layer (102), and having a mesa width smaller than that of the core layer (102). The two-step mesa optical waveguide includes a multi-mode optical waveguide region to which an electric field is applied or into which an electric current is injected, and a single-mode optical waveguide region to which the electric field is not applied and into which the electric current is not injected. When the mesa width of the core layer in the multi-mode optical waveguide region is defined as Wmesa1, and the mesa width of the core layer in the single-mode optical waveguide region is defined as Wmesa2, Wmesa1>Wmesa2 is satisfied.
