The present invention intends to provide a surface-emitting laser light source capable of generating a linearly polarized laser light having a single-lobed beam profile that takes the largest intensity value in its central area. A two-dimensional photonic crystal consisting of a plate member 31 with holes 311 or 312 arranged in a square lattice pattern is provided on one side of an active layer 23. The hole 311 or 312 is designed so that its plane shape on the emission side (plane “B”) is smaller than that on the active layer side (plane “C”). The center of gravity of the shape on plane “B” is displaced from that of the shape on plane “C” in the in-plane direction. This design lowers the degree of the in-plane symmetry of the two-dimensional photonic crystal, so that a linearly polarized laser light having a single lobe is obtained.

Disclosed is an internal combustion engine gas cycle modification process, comprising venting, which allows for some automatic gas transfer from intake to exhaust or vice versa, through the cylinder, in the compression or expansion strokes, by a second or third opening of either the intake or the exhaust valves, which is done by using a second or third auxiliary lobe on the intake or the exhaust cams, which however are much smaller than the normal lobes. Seven gas cycle modifications are explained and compared, each of which reduces NOx by 300-9,000× and cleans emission in the cylinder. On the same fuel consumption, all these modified gas cycles preserve torque and power. One however, increases high engine speed power and torque by over 70%. That may be exchanged for fuel savings. Double and triple lobe cams made the same way and cost the same as single lobe cams. It substitutes after-treatments.
