    Abstract: In a method for depositing a layer of amorphous hydrogenated silicon carbide (SiC:H), a gas mixture comprising a reactive gas to inert gas volume ratio of 1:12 to 2:3 is introduced into a reaction chamber of a plasma-enhanced chemical vapor deposition apparatus. The reactive gas has a ratio of Si of 50 to 60, C of 3 to 13, and H of 32 to 42 at %. The inert gas comprises i) a first inert gas selected from helium, neon and mixtures; and ii) a second inert gas selected from argon, krypton, xenon and mixtures. The reaction plasma is at a power frequency of 1-16 MHz at a power level of 100 W to 700 W. The resulting layer exhibits a refractive index of not less than 2.4 and a loss of not more than 180 dB/cm at an indicated wavelength within 800 to 900 nm.

    Abstract: An apparatus includes a slider body, a laser diode, an optical path, and a heating element. The laser diode is configured to produce energy and is subject to temperature changes as a result of producing energy. The optical path within the slider body is configured to deliver the energy to heat a magnetic recording medium. The heating element is disposed along a length of the optical path within the slider body and is configured to control a temperature of the optical path to mitigate temperature-induced mode hopping of the laser diode.
