Abstract
A near-field light generating device includes a substrate, a semiconductor laser device, a light absorbing device, and a near-field light generator. The semiconductor laser device is formed on the substrate and emits the laser light polarized in a first direction. The light absorbing device is formed on the substrate to be close to a light emission part of the semiconductor laser device and absorbs light polarized in a second direction orthogonal to the first direction. The near-field light generator is formed on the substrate to be close to a light emission part of the light absorbing device.
