    摘要： A ceramic cutting tool (100) is for high speed cutting of light, thin and soft materials. The ceramic cutting tool includes an upper blade (10) and a lower blade (20) both made of ceramic material. The upper and lower blades therefore possess extremely high hardness, and excellent wear resistance and heat resistance. This increases an operating lifetime of the ceramic cutting tool. Furthermore, the lower blade can alternatively be a lower blade assembly (30). The lower blade assembly includes a metal base (32), and a ceramic edge insert (31) detachably mounted in the metal base. If the ceramic edge insert becomes worn or is damaged, it can be easily replaced by a new ceramic edge insert. There is no need to replace the metal base.

    摘要： An inductive write head includes a first pole and a second pole that form a yoke having a write gap between the first pole and second pole. The second pole is formed of a particular Co100-a-bZRaCRb compound. More specifically, the second pole is formed where “a” is in the range of about 2 atomic percent to about 18 atomic percent, and “b” is in the range of about 0.5 atomic percent to about 6 atomic percent. The magnetic write element also includes a conductive coil which lies between the first pole and the second pole. The inductive write head also includes a first yoke pedestal attached to the first pole, and a second yoke pedestal attached to the second pole, with the write gap formed therebetween. Further, the first yoke pedestal has a pedestal width that defines the write element trackwidth and that is smaller than the pedestal width of the second yoke pedestal.

    摘要： Designs of multiplexing/demultiplexing modules configured for N channels are disclosed. One of the features in the designs is to provide at least one concave mirror for compenstating filter tilting errors. The concave mirrors is placed where an incident traveling distance of a light beam is substantially similar or equal to the reflected traveling distance of the beam such that the filter tilting errors successively introduced over a number of optical filters can be successively reduced, compensated or removed over a subsequent number of optical filters as the light beams travels.

    摘要： Techniques for designing optical couplers are disclosed. According to one aspect of the optical couplers, different from the prior art couplers, a holding tube (a sub-assembly) for holding an optical lens (e.g., a GRIN lens) and an optical filter (e.g., a thin film filter) is formed by concatenating two single tubes, one for accommodating the optical lens and the other for accommodating the optical filter. The two tubes are not required to have an identical dimension. As a result, inherent flexibilities are provided in the holding tube, especially the optical filter often comes in different sizes. Further, when the sub-assembly is inserted in a sleeve, only either one of the two tubes is secured to the sleeve so as to reduce a risk that, during a thermal condition change, any metal and glass material expansion will not cause the sub-assembly to be under stress that would otherwise be present when both of the tubes are secured to the sleeve. To reduce stress-related optical loss of the optical couplers, an epoxy adhesive is applied onto only a portion of an optical lens and a portion of a tube.

    摘要： Designs of optical devices particularly useful for separating channels signals that are originally multiplexed are disclosed. In accordance with one design, an optical filter configured to reflect a particular channel signal is positioned to receive a multiplexed signal at a small incident angle so as to minimize residuals of other signals in the channel signal. To further increase isolation from the other channel signals, another filter is introduced to transmit only the reflected channel signal, the another filter has a frequency response reciprocal to that of the original optical filter. One of the key advantages, benefits and objects of the designs is to increase channel signals separation efficiency by increasing isolation among separated channel signals.

    摘要： New designs of optical devices, particularly for adding or dropping a selected wavelength or a group of wavelengths as well as multiplexing a plurality of signals into a multiplexed signal or demultiplexing a multiplexed signal into several signals are disclosed. According to one aspect of the present invention, a reflected light beam from an optical filter is caused to go through the same optical filter at least one more time to minimize a residual signal embedded in the reflected light beam, wherein the residential signal is caused by the imperfect spectral characteristics of the optical filter. According to another aspect of the present invention, a reflective element is so positioned that the reflected light beam is bounced back to the optical filter. When the reflective element is another optical filter being substantially similar to that optical filter, the reflected light beam is equivalent to having transmitted. As a result, the residual signal in the reflected light beam is substantially minimized, resulting in great isolation for the R-channel from the T-channel.
