图 2为本发明实施例提供的一种光器件封装装置示意图;
图 3为本发明实施例提供的光器将封装装置中 TEC示意图。 具体实施方式
下面结合本发明实施例中的附图, 对本发明实施例中的方案进行清楚、 完整的描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是全 部实施例。 基于本发明实施例, 本领域普通技术人员在没有做出创造性劳动 前提下所获得的所有其它实施例, 都属于本发明保护的范围。
下面以图 1为例详细说明本发明实施例提供的光器件封装装置, 图 1为 本发明实施例提供的一种光器件封装装置示意图。
如图 1所示, 本发明实施例提供的光器件封装装置 200包括光器件 201 , 封装外壳 202 , TEC203o 光器件工作时所产生的热量可直接通过与之相连接的 TEC向外释放, 因此热阻部件大大减少, 提高了光器件的散热效率。
具体地, 本发明实施例所提供的 TEC203由 TEC冷端 204、 TEC热端 205 和电偶对 206组成, TEC热端的热端面电路上接装有 Pin脚 207。
TEC的具体结构示意图如图 3所示,图 3为本发明实施例提供的光器将封 装装置中 TEC示意图, 具体如下。
TEC冷端 204 , 在 TEC冷端 204的上端面上焊接有所述光器件 201。 TEC冷端可以为陶瓷电路基板,可以直接在 TEC冷端上端面上接装光器件 201 ; 如果在 TEC上蚀刻有冷端面电路, 则可以直接在 TEC冷端上端面上蚀刻 电路, 并且将光器件直接焊接在冷端面电路上。
其中, TEC冷端上蚀刻冷端面电路或者接装光器件, 而不使用专门的陶瓷 电路基板, 这提高了器件集成度, 在一定程度上减少了光器件封装装置的热 阻部件。
TEC热端 205 , TEC热端的上端面包括电偶对区域和电路区域, 所述电路 区域接装有 P in脚, 所述 P in脚提供所述光器件封装装置的外部上电接口。
TEC热端比 TEC冷端的平面面积大, TEC热端上除了与 TEC冷端之间的电 偶对区域外,还有用来蚀刻热端面电路或者接装 P in脚的电路区域, 并且 TEC 热端可以与封装装置的封装外壳 202组成一个封闭空间, 即 TEC热端的平面 面积大至足可以与封装外壳 202组成封闭空间。
其中, TEC热端上蚀刻热端面电路或者接装 P in脚,这提高了 TEC的集成 度, 在一定程度上减少了光器件封装装置的热阻部件。 并且在 TEC热端的上 端面的电路区域蚀刻电路的工艺简单, 降低了光器件封装装置的加工成本。
另外, 本发明实施例还在热端面电路域上接装 P in脚 207 , P in脚 207为 封装装置提供外部上电接口, 光器件可以通过所蚀刻的电路, 将 P in脚与光 器件进行电信连接, 以驱动光器将封装装置以及所包括的光器件进行工作。
具体地, TEC冷端的上端面和 TEC热端的上端面的电路区域中至少有一个 蚀刻有电路。 这存在三种情况, 即只在 TEC冷端的上端面上蚀刻有冷端面电 路; 或者只在 TEC 热端的上端面的电路区域中蚀刻有热端面电路; 或者即在 TEC冷端的上端面上蚀刻有热端面电路,并且还在 TEC热端的上端面的电路区 域中蚀刻有热端面电路。 图 3 中给出的是第三种情况下的 TEC示意图, 即在 TEC冷端和 TEC热端分别都蚀刻了电路。
当只在 TEC冷端的上端面上蚀刻有冷端面电路时, 所述光器件通过所蚀 刻的电路与所述 P in脚进行电信连接具体为: 所述光器件与所述冷端面电路 连接, 所述冷端面电路通过金线与所述 P in脚连接。 其中, 如果上端面上蚀 刻有冷端面电路, 则可以提供少数的接口给金线, 使用少数的金线即可通过 冷端面电路与光器件实现电信连接。
当只在 TEC热端的上端面的电路区域中蚀刻有热端面电路时, 所述光器 件通过所蚀刻的电路与所述 P in脚进行电信连接具体为: 所述光器件与金线 的一端连接, 所述金线的另一端与所述热端面电路连接, 所述热端面电路与 Pin脚连接。 其中, TEC冷端上没有蚀刻电路, 则可以使用较多的金线与光器 件进行金线键合, 实现电信连接。
当 TEC冷端的上端面和 TEC热端的上端面的电路区域中至少有一个蚀刻 有电路为 TEC冷端的上端面上蚀刻有热端面电路, 并且 TEC热端的上端面的 电路区域中蚀刻有热端面电路时, 光器件通过所蚀刻的电路与 Pin脚进行电 信连接具体为: 光器件与热端面电路连接, 冷端面电路与 Pin脚连接, 热端 面电路与冷端面电路通过金线键合。
本发明实施例提供的光器件封装装置只包括光器件, 封装外壳, TEC , 通 过在 TEC的冷端和 /或 TEC的热端蚀刻电路, 并在冷端面上直接焊接光器件, 在热端面上接装 Pin脚, 光器件通过所蚀刻的电路与 Pin脚进行电信连接, 由此便可通过 P i n脚上电, 以驱动光器件以及光器件封装装置。
由于该光器件封装装置中, 在 TEC的冷端和 /或 TEC的热端蚀刻电路, 提 高了 TEC的集成度, 因此光器件工作时所产生的热量可直接通过图 3所示的 TEC直接向外释放, 由此减少了封装装置的热阻部件,提高了散热效率。另夕卜, 由于本发明实施例提供的技术方案直接在 TEC 的热端蚀刻热端面电路, 所以 无须在封装外壳上嵌置陶瓷电路板, 进而降低了封装装置的材料成本和加工 成本。
相应地, 本发明实施例还提供了一种光模块, 该光模块中置入了上述光 器件封装装置, 还包括接收端。 其中, 光器件封装装置包括只包括光器件, 封装外壳, TEC, 通过在 TEC的冷端和 /或 TEC的热端蚀刻电路, 并在冷端面 上直接焊接光器件, 在热端面上接装 Pin脚, 光器件通过所蚀刻的电路与 Pin 脚进行电信连接, 由此便可通过 Pin脚上电, 以驱动光器件以及光器件封装 装置。 光器件工作时, 可以对电信号进行处理以得到相应速率的调制光信号, 通过光纤将调制光信号传送出去后, 接收端再把光信号转换成电信号。 由于 光模块中包括的光器件封装装置工作时所产生的热量可直接通过图 3 所示的 TEC直接向外释放, 由此减少了封装装置的热阻部件, 提高了散热效率, 因此 本发明实施例提供的光模块也在本发明实施例的保护范围内。
需要说明的是, 在具体应用中, 凡是使用了本发明实施例所提供的光器 件封装装置的器件, 如放大器等, 都在本发明实施例的保护范围内。
专业人员应该还可以进一步意识到, 结合本文中所公开的实施例描述的 方法和步骤, 能够以电子硬件、 计算机软件或者二者的结合来实现, 为了清 楚地说明硬件和软件的可互换性, 在上述说明中已经按照功能一般性地描述 了各示例的组成及步骤。 这些功能究竟以硬件还是软件方式来执行, 取决于 技术方案的特定应用和设计约束条件。 专业技术人员可以对每个特定的应用 来使用不同方法来实现所描述的功能, 但是这种实现不应认为超出本发明的 范围。
以上所述的具体实施方式, 对本发明的目的、 技术方案和有益效果进行 了进一步详细说明, 所应理解的是, 以上所述仅为本发明的具体实施方式而 已, 并不用于限定本发明的保护范围, 凡在本发明的精神和原则之内, 所做 的任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
