Optical chips are mainly used in the communication industry and are an indispensable part of the communication equipment system. The chip we often talk about is a silicon chip, which belongs to the semiconductor industry, such as CPU, storage, flash memory and so on. Core devices for optical chipsTo complete the conversion of photoelectric signal, is the core device, divided into active optical chip and passive optical chip. Optical chip includes laser, modulator, coupler, wavelength division multiplexer, detector and so on.
Optical chip refers to an electronic device manufactured on a semiconductor material for optical communication. It is a device that can convert electrical signals into optical signals, and has the advantages of high-speed transmission, large capacity, and low power consumption. The chip structure inside the optical chip is usually composed of an optical transmitter and an optical receiver. The function of optical chip: mainly includes light emission and light reception. The light emitter excites the light source through an electrical signal to produce an optical signalAnd send it out.

What is optical chip? The researchers combined the light-emitting properties of indium phosphide and the optical routing capabilities of silicon into a single hybrid chip. When a voltage is applied to indium phosphide, light enters the waveguide of the silicon wafer, producing a sustained laser beamImported stm32 chip, domestic industrial data acquisition card cost-effective, domestic chips successfully replace imported chips. The STM32 chip is mainly composed of a core and on-chip peripherals, and the STM32F103 uses a Cortex-M3 kernel, which is designed by ARM.
There is a gap between imported production technology and production process. Foreign production equipment advanced technology, excellent technology, the product parameters are stable, relatively durable, the appearance is more exquisite, not so rough. The tube core is not the same, the grade is divided, the grade of the Chinese imported tube core is compared, the purity of the infiltrated crystal is different, and the tube is made.Poor consistency and stability; That is to say, there is a quality gap between imported pipes and domestic pipes.
kernel is an upgraded version of Cortex-M3, compatible with Cortex-M3, to achieve Flash zero wait technology, no time to extract instructions, code execution efficiency is higher. In popular terms, the code execution speed has become faster. The same XX32F103 series chip, the main frequency, ST's maximum 72MHz, GD's can reach 108MHz, the code execution speed will be faster.
CKS32F103C8T6 and STM32F103CThe BT6 is both STM32 microcontroller chips, but there are some differences between them: Manufacturer: CKS32F103C8T6 is produced by China Advanced Science and Technology Group Co., LTD., while the STM32F103CBT6 is produced by STMicroelectronics. Program memory capacity: CKS32F103C8T6 has a Flash memory capacity of 64KB, while STM32F103CBT6 has a Flash memory capacity of 128KB.
The GD32 uses the M3 second generationWhile STM32 uses one generation, GD32's kernel-specific advantages make it different in performance. The GD32 has a maximum frequency of 108MHz, which provides higher computing speed compared to 72MHz or 64MHz for the STM32. In terms of power supply, the GD32 supports 6-6V, while the STM32 supports 0-6V (or even lower), which brings more flexibility to the GD32.

3, comprehensive chip. A flagship chip is the most powerful and comprehensive chip in a product line or a brand, used in high-end products with higher processing power, lower power consumption and stronger graphics processing capabilities. Flagship chip inWidely used in mobile phones, computers, tablets and other electronic devices, can provide a smoother user experience and higher performance.
1, the first point: the biggest difference between semiconductor light-emitting diodes and semiconductor lasers is that semiconductor light-emitting diodes have no resonator, are no threshold devices, its light is limited to the spontaneous radiation process, emit fluorescence, the biggest characteristics of semiconductor light-emitting diodes are: wide spectrum, good linearity, good temperature characteristics, low coupling efficiency.
2, the physical structure of the laser diode is to place a layer of photoactive semiconductors between the junctions of the light-emitting diode, and its end face has a partial reflection function after polishing, thus forming an optical resonator. In the case of forward bias, the LED generation emits light and interacts with the optical resonator, thereby further stimulating the emission of single-wavelength light from the junction, the physical properties of which are dependent on the material.
3, [error] The working principle of the light-emitting diode is different from the working principle of the laser, the laser emits stimulated radiation, and the light-emitting diode emits spontaneous radiation.
4,Light-emitting diodes (leds) are made of compounds including arsenic, phosphorus and nitrogen, which can radiate visible light when electrons and holes are combined, so they can be used to make light-emitting diodes. So what is the principle of transistors, lasers, light-emitting diodes? Transistors generally refer to all semiconductor devices, including more than N types.
5, LED light source itself does not contain mercury, lead and other harmful substances, no infrared and ultraviolet pollution, will not produce pollution to the outside world in use. LED science called light emitting diode, referred to as LED, is a solid state semiconductor device that can convert electrical energy into visible light, which can be straightThe connection converts electrical energy into light energy.
