摘要： A method of cutting an object to be processed comprises the steps of irradiating an object to be processed with a laser light which is an elliptically-polarized light having an ellipticity other than 1 such that a direction of polarization of the laser light intersects a line to cut the object and a thickness direction of the object, while locating a converging point of the laser light within the object, so as to form a modified region within the object along the line and generate a fracture from the modified region in the thickness direction of the object, and causing the fracture to reach front and rear faces of the object so as to cut the object along the line.

摘要： An object to be processed is restrained from warping at the time of laser processing. A modified region M2 is formed within a wafer 11, and fractures a2, b2 extending in directions parallel to the thickness direction of the wafer 11 and tilted with respect to a plane including lines 5 are generated from the modified region M2. A modified region M3 is formed within the wafer 11, and a fracture a3 extending in a direction parallel to the thickness direction of the wafer 11 and tilted with respect to the plane including the lines 5 is generated from the modified region M3 so as to connect with the fracture b2. That is, the fractures a2, a3, b2 are generated so as to be connected together. Therefore, at the time of laser processing, the fractures cause both side parts holding the lines to cut 5 therebetween in the wafer 11 to mesh with each other, whereby internal stresses occurring in a direction parallel to the thickness direction of the wafer 11 and perpendicular to the surface including the lines 5 when the modified regions are formed can be reduced.

摘要： A laser processing method is provided, which, when cutting an object to be processed comprising a substrate and a multilayer part, formed on a front face of the substrate, including a functional device, can cut the multilayer part with a high precision in particular.In a state where a protective tape 22 is attached to the front face 16a of a multilayer part 16, a substrate 4 is irradiated with laser light L while using its rear face 4b as a laser light entrance surface, so as to form a modified region 7 within the substrate 4 along a line to cut, thereby generating a fracture 24 reaching the front face 4a of the substrate 4 from a front-side end part 7a of the modified region 7. Attaching an expandable tape to the rear face 4b of the substrate 4 and expanding it in the state where such a fracture 24 is generated can cut not only the substrate 4 but also the multilayer part 16 on the line to cut, i.e., interlayer insulating films 17a, 17b, with a favorable precision along the line to cut.

摘要： An optical transmission device capable of preventing deterioration in the transmission quality of a signal beam. A wavelength-multiplexed signal beam from a transmission path is split by a splitter, and the split signal beams are input to first and second optical paths, respectively. An add/drop unit for adding/dropping a wavelength-multiplexed signal beam is removably insertable in the second optical path. A switch outputs the wavelength-multiplexed signal beam, received from one of the first and second optical paths, to an optical amplifier. The optical amplifier amplifies the wavelength-multiplexed signal beam output from the switch and outputs the amplified signal beam to a subsequent circuit. A supervisory controller collects alarm information from the optical transmission device as well as from other optical transmission devices, and controls the switch in accordance with the collected alarm information such that the wavelength-multiplexed signal beam from the second optical path is input to the optical amplifier.

摘要： During initial start-up of an optical communication system, an ASE reference span loss is calculated based on transmitting power and received power of ASE light generated by an optical amplifier, and an OSC reference span loss is calculated based on the transmitting power and the received power of OSC light. During normal operation of the optical communication system, a span loss is calculated using the OSC light, and an amount of change in the span loss representing a difference between the span loss and the OSC reference span loss is calculated. A current span loss between a transmitting station and a receiving station is calculated by adding the amount of change in the span loss to the ASE reference span loss.

摘要： In an optical transmission system, a controller acquires a noise light loss value, which indicates a loss that noise light output from an upstream-side optical amplifier undergoes during propagation to a downstream-side optical amplifier through an optical loss medium, and a signal beam loss value, which indicates a loss that a signal beam output from the upstream-side optical amplifier undergoes during propagation to the downstream-side optical amplifier through the optical loss medium, obtains, as a loss difference, a difference between the noise light loss value and the signal beam loss value and, when setting up the downstream-side optical amplifier, determines the gain of the downstream-side optical amplifier by compensating the loss difference.

摘要： A laser processing method is provided, which, when cutting a substrate formed with a laminate part including a plurality of functional devices into a plurality of chips, each chip including at least one of the functional devices, can cut the laminate part with a high precision together with the substrate.In this laser processing method, modified regions differing from each other in terms of easiness to cause the substrate 4 to fracture are formed along respective lines to cut 5a to 5d. Therefore, when an expandable tape is attached to the rear face of a substrate 4 and expanded, an object to be processed 1 is cut stepwise into a plurality of chips. Such stepwise cutting allows uniform tensile stresses to act on respective parts extending along the lines to cut 5a to 5d, whereby interlayer insulating films on the lines to cut 5a to 5d are cut with a high precision together with the substrate 4.

摘要： A laser processing method which can reliably form a modified region within an object to be processed along a desirable part in a line to cut is provided. This laser processing method irradiates a substrate 4 with laser light L while locating a light-converging point P within the substrate 4, so as to form a quality modified region 71 to become a starting point region for cutting within the substrate 4 along a line to cut 5. Here, the laser light L is oscillated pulsewise along a desirable part RP in the line to cut 5, and continuously in a predetermined part RC in the line to cut 5. Consequently, the quality modified region 71 is formed within the substrate 4 along the desirable part RP in the line to cut 5, whereas no quality modified region 71 is formed within the substrate 4 along the predetermined part RC in the line to cut 5.
