A Vertical Cavity Surface Emitting Laser capable of providing high output of fundamental transverse mode while preventing oscillation of high-order transverse mode is provided. The composition is suitable for use in fire-resistant, low-smoke hose. The optical waveguide accommodating section includes at least two jacket parts that can be connected to each other, wherein at least one jacket part can be fastened to the pin accommodating section using a joint so that the jacket part can be swiveled about a certain swivel angle between an open position and a closed position.
