摘要	Devices and methods are provided to reduce the wake-up time of a Vertical Cavity Surface Emitting Laser (VCSEL) used in a data communication link. For example, in one aspect, a method for optical communications includes, in an optical communication device including a light-emitting device, applying a bias current to the light-emitting device and transmitting a pulse to the light-emitting device before transmitting a preamble signal or data signal to the light-emitting device, wherein the pulse has a voltage greater than a highest voltage of the preamble signal or data signal.
其他摘要	提供了用于减少数据通信链路中使用的垂直腔面发射激光器（VCSEL）的唤醒时间的装置和方法。例如，在一个方面，一种用于光通信的方法包括，在包括发光装置的光通信装置中，向发光装置施加偏置电流并在发送前导码之前将脉冲发送到发光装置。信号或数据信号到发光装置，其中脉冲的电压大于前同步信号或数据信号的最高电压。
主权项	A method for optical communications, comprising: in an optical communication device comprising a transmitter including a light-emitting device, applying a bias current to the light-emitting device; and transmitting a pulse as an input to the light-emitting device before transmitting a preamble signal or data signal to the light-emitting device, wherein the pulse has a voltage equal to or greater than a highest voltage of the preamble signal or data signal.
