The more frustrating the brave can show its spirit! Even though Apple's plans to adopt sapphire have been repeatedly blocked, their interest in this material has not diminished.
In October last year, Apple's sapphire glass production partner GT Advanced Technologies officially announced its application for bankruptcy protection. Recently, it has been reported that a new agreement has been reached between GT Advanced Technologies and Apple. The content is mainly GT can be used in other Ways to pay off their $439 million in debt to Apple.
Specifically, GT will auction their production facilities on November 23, including approximately 600 sapphire furnaces. You may feel that Apple may have no interest in sapphire at this point.
But this is not the case. Even though the relationship with sapphire supplier GT Advanced has developed to such a situation, Apple's interest in sapphire is undiminished.
Earlier this year, Apple also applied for a patent related to sapphire cutting technology. The patent is called "System and Method for Laser Slashing Sapphire Using Multiple Gas Media." It introduces a new method of laser cutting sapphire. Apple also clearly stated that this cutting method is mainly used to cut the cover glass used in portable mobile devices. . These devices include iPhone, iPad, iPod, and Apple Watch.
There is also a ceramic surface called "Electrical Device Case", which shows that Apple is developing a new sapphire screen technology. Apple plans to use a laser ablation technique to etch a wedge-shaped groove on a sapphire sheet with a thickness of 0.3-1.0 mm while cooling the material with a jet to remove the melted ceramic. Then Apple will borrow the shell design on the iPhone, and add the corresponding bulge on the side to fit the groove on the sapphire glass to form a strong and seamless interlocking structure.
Apple also plans to add ceramic reinforcements to the outer casing, such as ceramic fibers. In addition, Apple has obtained a number of technical patents related to sapphire.
Since Apple signed a contract with GT Advanced, the rumor that the iPhone will be equipped with a sapphire glass screen has never been broken. Even though GT Advanced is now bankrupt, the industry is still very concerned about Apple's use of this material.
Compared to the competitor Corning Gorilla Glass, sapphire glass has a stronger scratch resistance. However, Corning has always stressed that sapphire glass is not as perfect as people think, not only is it expensive, but also heavier and more fragile.
For now, Apple's sapphire glass plan is full of uncertainties, which is undoubtedly good news for Corning, after all, because the difficulty of sapphire processing is not generally high, and Apple wants to use this on a large number of devices. Materials, whether for material collection and factory processing, are very difficult challenges. Not only does Apple need to get the technology in place, but it also needs to find reliable partners and provide them with adequate supplies.
Optical coupler is also called optical splitter, is one of the most important passive devices in optical fiber link, is with multiple inputs and multiple output end of the optical fiber connected devices. The fiber optic splitter by the light splitting principle can be divided into the fused biconical taper (FBT type) and planar waveguide type (PLC type).
