The laser chip listed company Everbright Huaxin opened high and closed at the daily limit. The Western Securities Electronics Team pointed out that RoboSense, Hesai and others have launched a number of new laser radar products, and there is great potential in the field of robotics. In this regard, the reporter called Everbright Huaxin as an investor, and the staff said that they have been supplying RoboSense and Hesai in small batches. When asked whether there will be a large volume next year, the staff said that it is necessary to pay attention to the market situation, because mainstream manufacturers have not fully adopted laser radars, and the penetration rate of new energy vehicles is also average. Except for Huawei, which uses more, other manufacturers have not fully followed up. It is worth mentioning that Everbright Huaxin also stated that the company's single-wave 100Gbps electro-absorption modulator laser diode (EML) chip is the core component of the current 400G/800G supercomputing data center interconnect optical module. When talking about whether to supply domestic optical module companies, the above-mentioned personnel said that they are still in contact, many of them are in the negotiation and discussion stage of early cooperation, and some have small batches of supply.
